Fix for ‘Software Licensing service Has Stopped’ on some Vista 64bit systems RRS feed

  • General discussion

  • If you receive the following error “Software Licensing Service Has Stopped” it may be caused by a specific Registry Key being deleted. This Registry Key tells Vista the location of the file slsvc.exe, which is the file that runs the Software Licensing Service. This will cause Windows Validation to fail.

      We believe this Registry key is being deleted by some Registry Cleaner programs and currently appears to only affect 64bit versions of Vista.

     

      To determine if your issue qualifies as one that would be resolved by this fix, please confirm your issue matched ALL of the below criteria. If it does not, please Do Not attempt the Resolution Steps at the bottom of this thread.

    A) Your Vista is a 64bit version

    B) Diagnostic Report shows code "0x80070426" after line "Online Validation Code:"

    C) Diagnostic Report Does Not show any numbers after line "TTS Error:"

    (You can generate a Diagnostic Report by downloading and running MGADiag Tool at http://go.microsoft.com/fwlink/?linkid=52012

    If your issue fits criteria A), B) and C), please continue to criteria D)

      If this post resolved your issue and you suspect a specific program may have caused the issue (i.e. you suspect the program may have deleted one of your Vista’s Registry Entries).  Please create a forum thread (by clicking the “New” dropdown menu, on the Vista forum main page, and select “General Discussion”) and tell us the program’s Name and Version (and if you downloaded it, where from) so we can test it out.
