install error

[mixmaster]

ok, I have a weird problem.

I have done nothing to change any configurations on my computer. Today, I got on to install something and I get the error "InstallShield 255: Error Installing Microsoft(R) .NET Framework" and it won't let me download.

I'm trying to download Alibre Design Xpress (from the Alibre website, so it's legal). As far as I can tell, it's only doing this for this one download.


any ideas????

Create a Restore point manually first.

Try to install Windows Installer 3.1 V2 (http://www.microsoft.com/downloads/details.aspx?FamilyId=889482FC-5F56-4A38-B838-DE776FD4138C&displaylang=en&displaylang=en) (skip this if you run Vista or Win7)
then try manually installing/updating .NET Framework 3.5 SP1 (http://www.microsoft.com/downloads/details.aspx?FamilyID=ab99342f-5d1a-413d-8319-81da479ab0d7&displaylang=en#Requirements) (not needed for Win7) then run Windows update after that.
