Just switched to Win 10 from Win 8.1. A program is giving an error at startup (C:\Windows\Microsoft.NET\Framework\v2.0.50727\mscorlib.tlb could not be loaded) so I tried to reinstall .NET Framework.
I've tried with all the possibilities I've found and even installing some components that indirectly install it but alway it ends with:
.NET Framework 3.5 (includes .NET 2.0 and 3.0)
The system cannot find the file specified. Error code 0x80070002
I've spent a lot of time searching possibilities, let's see if anyone has a clue or an undesired revert to Win8.1 is on the horizon...
UPDATE: From the suggestion in a comment by @magicandre1981: Can't install .net 3.5 on Windows 10
DISM.EXE /Online /Add-Capability /CapabilityName:NetFx3~~~~
And it worked! 100% completed without problems. Now almost all is fixed except when I try to open a Properties window on Visual Studio 2008 (the main user of the .NET 3 it says
Failed to create .NET Frameworks PropertyGrid component. Please verify that the Common Language Runtime and .NET Frameworks are properly installed.
Haven't dug deeper but I hope to fix this -hopefully- last one.
If you have windows 10 installation media (DVD, ISO, USB) attach it. Run
cmd as admin and run:
dism /online /Enable-Feature /FeatureName:Netfx3 /All /LimitAccess /Source:E:\sources\sxs
E:\ is the drive letter assigned to installation media. If you still get error, you have to uninstall every update to NetFx4.5, then repeat steps above, and again update NetFx4.5 as stated here. Also check out here if you're joined to domain.
