Hi, I've searched around for possible fixes for this problem but I had no luck in being able to install .NET.
A few seconds after attempting to install Microsoft .NET Framework 4 Client Profile, a message pops up, saying that".NET Framework 4 has not been installed because:
The requested operation failed. A system reboot is required to rollback changes made."
Methods I've tried:
1. Uninstalling my current .NET Framework 4, then rebooting/restarting and reinstalling .NET
2. Using the .NET Framework Cleanup Tools to clean all versions of .NET, rebooting then reinstalling
3. Installing while my computer was in a clean boot state
Regardless of what I do, all of these methods ended up with the same "system reboot is required" message after failed installation. It seems that rebooting/restarting my computer wouldn't do anything..
I've used the .NET Framework 4 (Standalone installer) for these methods.
If it helps (doubt it), I was initially trying to install AutoCAD on this computer, and realised that AutoCAD wouldn't install because of .NET Framework 4 being either outdated or not on the same version as AutoCAD requires.
Thanks.
