Fatal Error when launching SD 4.4 (CLR Error: 800004005)

Hi,

I just installed SD along with .Net and WinSDK.

I have removed previous versions of .Net, rebooted, cleaned up all left overs (directories), reinstalled , rebooted to no avail.

The error message pops up right after I double-click on the icon to start the program (SharpDevelop.exe)

CLR Error: 800004005

The versions I have installed are as follows.

WinSDK 10.0.30514.1
.Net 4.5.50938.18408
Microsoft Visual C++ 2010 Redistributable 10.0.40219

Sharp Develop 4.4.1.9729

Google tells me this is related to .Net but I have followed all the instructions I could find and nothing worked.

Any help would be greatly appreciated.

Thanks in advance.
