Problem Description

Error "Error 1181/0x91 ('System error 0x91 (The directory is not empty.)') occured while deleting directory 'C:\ProgramData\KasperskyLab\adminkit\1103''" when installing Network Agent.

How To Fix

1. Make sure that the folder ‘C:\ProgramData\KasperskyLab\adminkit\1103’ actually exists. 
2. If you can navigate to this folder in Explorer (with "Hidden items" enabled), try to delete or rename this folder and repeat installation.
3. If you can't find this directory, then please try to navigate to ‘C:\ProgramData\Kaspersky Lab\adminkit’ folder in the terminal (cmd) from NT AUTHORITY\SYSTEM account.
4. Then check its contents with the "dir" command.
5. If the folder appears on the list, then try deleting it or renaming it. Here you probably will need an option with CMD: rmdir /S /Q "C:\ProgramData\KasperskyLab\adminkit\1103" " (in order to remove) or ren "C:\ProgramData\KasperskyLab\adminkit\1103" “1103_old” (in order to rename).

Do not forget to perform all actions from an account that has local administrator rights on this computer with elevated privileges (from the Administrator), if UAC is used.
