.NET Framework 4 won't install

Sep 22, 2012 9:10AM PDT

For some reason I cannot install the .net framework that is needed for a lot of software. I have tried installing it from the Microsoft website directly and through other software installation programs. I just did another attempted install from the Microsoft website and here is my full report:

Clarification Request
Install message error
Sep 23, 2012 8:34AM PDT

If you look in the installation report you can see that there is this error:

[9/22/2012, 18:58:51] Returning IDOK. INSTALLMESSAGE_ERROR [Service 'Windows Presentation Foundation Font Cache 4.0.0.0' (WPFFontCache_v0400) could not be installed. Verify that you have sufficient privileges to install system services.]


I don't know how I would go about fixing that.

I use Comodo antivirus software which includes a type of 'defense' system for my registry. I just disabled that feature and it installed perfectly fine on the first try.......

Thanks for the help and sorry for the waste of time Silly

So did you try the old .NET cleaner? Link follows.

Used cleaner based on suggestions from other threads

I did use the cleaner in that link based on a suggestion in this thread where the guy seemed to be having the same issue as me.

I also tried installing Windows Installer 4.5 and using it to repair files because of this thread

Forgot to mention that I am running XP Pro SP3

Not sure if this helps but I do have a folder in my "WINDOWS\Microsoft.NET\Framework" directory named "v4.0.30319" which has files in it.

See above

I see that the issue of PROTECTION or Antivirus suites was noted. So with that noted, why not delete that folder after you used the cleanup tool?
