I used something called Dependency Walker (
www.dependencywalker.com) on the executable, and it seems like there are some dependencies...missing of course:
API-MS-WIN-CORE-COM-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-ERROR-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-ROBUFFER-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-STRING-L1-1-0.DLL
API-MS-WIN-SHCORE-SCALING-L1-1-0.DLL
DCOMP.DLL
IESHIMS.DLL
I think this is part of the basic .NET infrastructure, and it was broken by the Tera online installer imo. Why it only affects D2 I do not know, and what exactly will restore these files easily (like vcredist 2008, 2010, etc.) I cannot locate.
Any ideas?
