No, I suppose we were not talking about RegSupreme (I do not know anything about it…). Anyway, there are some links you can try:
RegClean for Windows 98 (but works on XP)
BeClean Specially the Registry Cleaning feature
But the best, you can make a download for try, is PowerTools. Very powerful registry power tools, with lots of extra options]very powerfull registry power tools, with lots of extra options. Unfortunately, it’s a shareware.
I do not have the file you mentioned: c:\windows\system32\mssmgrie.exe
I tryed a Google and Microsoft search and nothing…
I strongly suggest you this:
- Download avast! 4.1.289
- Desinstall your actual version of avast (Control Panel).
- Boot
- Run PowerTools and choose Registry cleaning. You can choose the option of a backup of the removed itens.
- Use Avast Uninstall for complete desinstallation.
- Boot
- Install the downloaded 4.1.289 version.
Anyway, if you need another licence key, the registration form can be found here.
