Further Information and Manual Repair
To successfully overcome this problem and ensure the successful installation of Kaspersky Internet Security software on your system, try the methods given below.
Method 1- Remove the Leftover Registry Key
Sometimes Internal error code 2771 may appear during installation due to the leftover registry key from the previous Kaspersky software removal.
A registry key is often created when uninstalling the previous Kaspersky version from the PC. This key is left behind even after you reboot your system.
This key is called AVP**_post_ uninstall, you need to delete it to ensure the new version of the Kaspersky program is installed successfully on your PC. For this, simply go to the start menu and type Regedit in the search bar.
Now navigate to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun and then look here for the registry key called AVP**_post_ uninstall. In order to delete this file, right-click it and then select delete.
Once uninstalled, reboot your PC and then try installing the Kaspersky Internet Security program again.
Hopefully, this will resolve the issue. If the software installs smoothly, then the error is fixed, in case it still persists, then try other methods illustrated below.
Method 2 – Remove the INFCAHCE.1 Corrupt File
Another reason for the error pop-up may be INFCAHCHE.1 corruption.
This file is basically used to store driver information and inf file locations. However, if it contains corrupted information, then you must remove it.
To do this, go to the start menu and type cmd into the search bar. This will open a command prompt. Here type del C:\Windows\infinfcache.1. Now reboot your PC and try installing Kaspersky software on again.
Method 3 – Fix Software Conflict
Security software conflict can also result in internal error 2771 code display. And when this happens, the installation of Kaspersky prematurely ends.
Security software conflict may occur if you have Comodo Firewall installed on your PC. A firewall is known to cause issues with Kaspersky software programs.
The best way to resolve this issue is to uninstall all security software programs on your PC. Once all security software is removed, then install Kaspersky on your system. If the installation is successfully completed, then reinstall the other software again.
