TESO launcher hangs at "Loading..."

[Baertram]

Hey guys,

I had to reinstall my PC and i'm on Win10 64bit currently.
As I tried to start the TESO launcher (admin or not) it will always hang and show the background image + a text "Loading..." ("Lade..." -> German client).

I tried several things that I found in the forums and the internet, like install/uninstall sata drivers, intel chipset drivers, microsoft c++ 2010 redist from the TESO_install.exe setup that we can download at the TESO websites (login -> downlaod game), disable firewalls, disable antivirus, etc.

Nothing seems to help

The launcher's log (host.developer.log) file is showing me the following error message:
03/18/2016 12:10:55 Unable to load library (C:\Games\TESO\Launcher\MinSpecDetectionInterop.dll) (193)

Someone wrote in a forum that it could have to do with the SATA drivers and that the harddrives are not recognized correctly.
I updated all drivers and checked the system information, dxdiag, everyhting...

I appreciate every addiitonal tip how I could solve this error. Currently I'm not able to play as I cannot update the game :-(
