Had this (related?) issue:
Taken from unity crash report (error.log):
"
Unity Editor [version: Unity 2017.2.1f1_94bf3f9e6b5e]
VSFilter.dll caused an Access Violation (0xc0000005)
in module VSFilter.dll at 0033:6dc969f5.
…"
Solved it this way:
- open “cmd” under admin rights
- unregister via: regsvr32 /u VSFilter.dll
There is no need to register it after these steps.
