Dot Net 4.0.30319 Initialization error

Question

Running Windows 7. Been getting the attached error for a few different programs recently. More or less Windows doesn't detect my installed version of Dot Net.

Been googling all over the place, haven't found a solution that works. More or less, lots of uninstall/reinstalls are suggested which hasn't worked.

Any pointers?

You may actually need to install .NET 4.5. The version number for .NET 4 and 4.5 is the same (4.0.30319), as 4.5 is an in-place upgrade to 4.0.

The only version difference is the build number, which is not being reported in that dialog.

Thanks for the advice. No luck though, figured out I have this issue (mscoree.dll version 2, not updated by .Net 4). Working through those steps now... http://blogs.msdn.com/b/vsnetsetup/archive/2011/05/20/net-framework-initialization-error.aspx – 1111000110 Sep 01 '13 at 14:25

Sounds like you may be having a registry issue.

If installing the newer version of 4.5 doesn't resolve your issue, you may need to look into uninstalling and re-installing your .NET application.

You can also detect if your Registry Keys are showing the correct version here :
