They were under the misimpression that Net 4.0 was a newer version of Net 3.5. Sorry no. I'm not going to reproduce the web here.
If you need 3.5, then you install 3.5.
I was running MS NET Framework 3.5 smoothly under Windows 7. For no good reason, I decided to update to a more recent version. That’s when all my problems began. I now can’t open some key programs that use NET Frmk to work.
I’ve removed NET Framework a number of times with an uninstaller. As far as I can tell, I purged all files and registry entries. I’ve done this in Safe Mode and Normal Mode.
I tried installing older and newer versions. Always problems. I now have v4.5 installed.
- When I start some programs, I get a message that NET Framework will not load. Other times, I get a .NET Framework Initialization Error [Please
set registry key - HKLM\Software\Microsoft\.NETFramework\InstallRoot to the .NET Framework install location]. I have entered this into the registry manually, but no luck.
- I have tried turning on the feature in Control Panel. I get a message that “An error has occurred. Not all the features were successfully changed.”
- If I check ‘Services’ in MSCONFIG, it shows the 64 & 86 versions are both Stopped.
- I have tried “NetFxRepairTool’, but it “is unable to resolve the installation issues”.
- I ran “NetFxSetupVerifier” and it was also unsuccessful.
Any suggestions as to how I get back on track?
