Summary

Product:	F-PROT Antivirus for Windows
Version:	6

Installation almost completes, but ends up rewinding and producing a fatal error

When installing F-PROT Antivirus, you get to as far as 80% of the "copying files" process. After that, the installation stops for a second, then rewinds (rolls back) and you get a "Fatal error: Installation ended prematurely because of an error." After you click OK the installer quits.

The cause: A previous installation may have left some information in the Windows driver store.

The solution:

Delete the FRISK Software folders in the following paths:

• C:\Documents and settings\All users\Application data\
  or %allusersprofile%\Application data\
• C:\Program files\
  or %programfiles%\

Now navigate to C:\Windows\System32\Drvstore (or %systemroot%\System32\Drvstore) and check whether it contains a folder named FPAV_RTP_xxxxxx (where xxxxxx is variable). Delete this folder if it exists.

When these folders have been deleted, run the installation again and it should complete successfully.

If this does not work, please reinstall F-PROT Antivirus at the command-line with the log switch. Please use the following command:

msiexec /i <filename.msi> /lv C:\fpav_install.log

You may send the log file name "fpav_install.log" located in drive C at support@f-prot.com so we can diagnose the installation error properly.
