Unable install


When I install Time Machine I receive the following error message:

“Returnil Virtual system is currently install in this computer…”

But I have ready uninstall this software, What can I doing now?



What operating system do you have (Windows 7, Vista, XP, etc)?

Is there still a Program folder left over from it? (Go to whichever drive/partition Windows is installed on, usually “C”. Then go to the “Program Files” folder. Find and delete the folder “Returnil”, or similar. C:\Program Files\Returnil)

If that doesn’t help, or if the folder isn’t there, download and run CCleaner.

All don’t work!

Pls check the following items, if exist, you can delete it

  1. “HKLM\SYSTEM\CurrentControlSet\Services\RVFsSec”
  2. %windir%\system32\drivers\RVFsSec.sys

Done, Thanx
