Letter from a reader:

The program cannot be removed from the computer through the Add/Remove Programs menu and by no means at all, deleted all folders related to the program, used all kinds of utilities that clean the registry of unnecessary keys, it’s useless. The fact is that I want to install it again, it is licensed and purchased for money, but recently it has been working with errors. The installation program says: the application is already installed and that’s where it ends. The forum suggested what to look for in the bushes (in the registry). It's a joke? Help.

The program cannot be removed from the computer

And of course, the program or game cannot be installed again, because the utilities Unlocker, CCleaner, Revo Uninstaller and the like may be useless. On one site I read how, using one of these programs, you can remove an antivirus program, I laughed for a long time, in reality, of course, everything will not be so, sometimes the principles of operation of these programs turn out to be ineffective. Let's think about what we will do if all the above-mentioned programs did not help us.

The information in our article applies to Windows 7 and Windows 8. 1.

Many in case of failure with removing a program from your computer they even reinstall the operating system when it comes to their favorite game. Believe me, in most cases this is not necessary. By the way, it’s also about the accumulation of garbage in Windows, because the remains of the program are somewhere and of course take up space on the hard drive, all this is quite unpleasant and of course I want to know where exactly the remaining program files are located. This kind of trouble occurs because, for some reason, the connection between the program and its keys in the registry is broken. There are many reasons for these, ranging from incorrect user actions and errors in the program itself; we will not dwell on this. To solve such problems, we will need to manually make changes to the registry and our program will be completely removed. How to do it?

Is the program you want to remove no longer in use? If you know the process related to it, you also need to end it in the device manager.

The best thing to do is disable the program service in Computer Management.

Now delete all files related to the program from your computer, start with its personal folder located in Program Files, then reboot; if the program is not deleted and it cannot be installed again, you will have to delete its entries in the registry.

It is advisable to view the entire registry or branches HKEY_LOCAL_MACHINE (contains information about hardware and software) and HKEY_CURRENT_USER\Software, where all information about installed applications is located.

What else can you do if you have problems uninstalling programs?

• Try to visit the website of the program manufacturer, there is a high probability that an uninstaller is available for download there, for example, on the website of the Nero program, which is not so easy to uninstall, there is such a utility.
• If you uninstall a game or program without success, the uninstaller may be located on the installation disk, you should run it and you will see the Delete option, if you do not have the disk, read on.
• In especially difficult cases, you will have to enter your operating system in Safe Mode, only in it you will be able to disable the service and delete all remaining files and registry keys.
• Sometimes you will not be able to delete program files even in Safe Mode, but you will be able to rename them and delete them after a reboot.
• It is worth trying to reinstall the program, and then it will be successfully removed.

For clarity, let's try to reinstall the game Call of Duty 4: Modern Warfare, which my son’s comrade in arms cannot reinstall for several days in a row.

In the section on the question How to contact the system administrator???? given by the author Say goodbye to Christ the best answer is If this is a home computer, you don’t need to look for any system administrator. You need to look for the person who configured Windows. Because there is an account that has the right to install/delete applications, but yours is limited. All you need to do is enter the name and password of that account. Unfortunately, I can't say more. If you don’t have this information, you can cheat, but you can’t do it without a specialist.

Answer from Andrey Petroff[guru]
Where is the description of the operating system? Have you looked at the user's rights? Use a user with administrator rights.

Answer from troch[guru]
When you turn on the computer, all users are displayed there, for example: You, Sister, Dad. One of these accounts is an Administrator and only he can delete this game. You can find out who the admin is like this: Start Menu/Control Panel/All Control Panel Elements/User Accounts and there it will say Administrator under the picture. You can only delete it from this account.

Uninstalling some applications may fail because a window will appear stating that " Insufficient permissions to delete. Contact your system administrator" Most often, the cause of the malfunction is that the uninstaller utility did not find the parameters necessary for uninstallation in the registry.

Solution

The first step to solving the problem is to boot the OS in safe mode and repeat the removal attempt. If this does not help, then try the following methods, first closing the uninstall window and making sure that the uninstaller utility is not running in the Task Manager:

1. Lower your account control criteria. Follow the path: “Control Panel” => “User Account Control” => “Changing User Account Control settings.” In the window, move the slider to the very bottom, confirm the change by clicking OK.
2. Use third-party uninstaller utilities. This could be Uninstall Tool or CCleaner. In them you only need to select the problematic application and confirm its uninstallation.
3. Check your computer for viruses.
4. Roll back the system to a previous restore point.
5. Change permissions. To do this, go to the directory where the problematic application is located. In it, right-click and follow the path: “Properties” => “Security”. In this tab, you need to set full access to all groups and users. Select each line and click on “Edit”, after which the corresponding option will become available.

If none of the above resolves the error " Contact your system administrator“, this means the application is so persistent that it will not “survive” only a reinstallation of Windows.

When trying to uninstall a program, Windows OS users may encounter a message stating that they do not have enough rights to perform this operation: “Insufficient rights to uninstall Please contact your system administrator.” The message also recommends that you contact your system administrator for help, while the user himself may be such a system administrator and have the appropriate rights. The solution to this problem will be a set of actions that I will outline below.

When you install a program on a PC, its files are copied to various folders, entries are made in the registry, the necessary libraries are registered, and file associations are registered. Then a special key is added to the registry, by which Windows can find the installed program.

All of the above operations are recorded in a special log file, which is usually located in the main program folder along with the uninstaller file.

When a person tries to remove this program, Windows looks for a registered uninstaller program in the registry and launches it. Using the log file mentioned above, the uninstaller undoes the changes made during the installation of this program. It removes all files that were copied, all created registry keys, and any other “traces” present.

If Windows does not find the log file, or does not find records of changes made in the registry, then the uninstaller will not be able to correctly remove the program, and you will receive a system message “Insufficient rights to uninstall. Contact the administrator."

Such a lack of a log file or change record may be caused by the following reasons:

• Damage to the system registry (virus programs, incorrect user actions, gradual clogging of the registry over time, improper shutdown of the PC, etc.);
• Problems with the hard drive (the appearance of bad sectors, its shedding, etc.);
• Accidental or intentional deletion of a log file by the user.

In rare cases, the error may be caused by a mismatch of access rights between multiple users on the system.

As for the most frequently reported “problematic” programs, they are usually torrent clients and various gaming software.

How to fix the problem of lack of permissions to delete

Solving the dysfunction of not having the necessary rights to delete can be done in various ways, which we will consider below in ranking order. Before performing these methods, I recommend ending the process of the program to be removed in the “Task Manager” (if available), since without this operation, correct removal of the software may become impossible.

Method number 1. Use Safe Mode

Restart your PC in safe mode (to enter it, quickly press F8 after turning on the computer), and try to remove the problematic program. This usually works out very easily.

Method number 2. Change the UAC value

Another way to solve the problem is to lower the User Account Control (UAC) value.

1. Go to Control Panel, select "User Account Control", then click on Change Accounts.
2. Move the UAC slider to the lowest value (“Never notify”), reboot the PC, and check the result.

Method No. 3. Use a specialized uninstaller

Specialized solutions such as “Uninstall Tool” and “Revo Uninstaller” have shown good effectiveness in removing problematic software. It is enough to install and run the mentioned programs, select the software needed to remove them, and click on “Delete”.

Method number 4. Check your PC for viruses

In some cases, malware is the direct cause of the inability to remove any software. Check your system for viruses, with Dr.Web CureIt! ", "AdwCleaner" and other proven analogues.

Use AdwCleaner to remove malware

Method No. 5. Activate the hidden administrative account

In some operating systems (for example, Windows Vista), the administrator account may be hidden. To correct the situation, enter at the command line:

net user administrator /active:yes

and press enter.

Method number 6. Set the appropriate permissions

Go to the uninstall programs panel (click on “Start”, enter appwiz.cpl in the search bar and press enter). There, move the mouse cursor to an empty space, right-click, select “Sorting” - “Details”.

In the list that opens, check the box next to “Location”. Now we will see where the folder with the problematic program is located.

We go there, select this folder, click on the right mouse button, and select “Properties” in the menu that appears. In the window that opens, go to the “Security” tab.

We select each of the users listed above in turn, click on “Edit”, and in the permissions we give them full access. After completing all operations, reboot the PC and try to remove the problematic software.

Method No. 7. Use system rollback

If all else fails (which is extremely rare), I recommend using a system rollback. Click on “Start”, enter rstrui in the search bar, then press “enter”. Select a stable point and roll back the system to the specified state.

Conclusion

Solving the problem “Insufficient rights to delete. Contact your system administrator." will be a set of methods described by me above. The greatest effectiveness has been shown by the use of third-party installers (the “Uninstall Tool” level), which allow you to get rid of unnecessary software in just a few seconds.
