Running executables through MO works perfectly, but closing them is a different story. Every time I've run any of SSEEdit, LOOT, Wrye Bash, or Mator Smash through MO and then tried to close them, I'm given a crash and an error message; furthermore, anything which should be going to the overwrite folder is instead being dumped in the main SkyrimSE directory instead. Here's what I'm shown upon an SSEEdit crash:
Problem signature: Problem Event Name: APPCRASH Application Name: SSEEdit.exe Application Version: 184.108.40.206 Application Timestamp: 58621831 Fault Module Name: usvfs_x86.dll Fault Module Version: 0.2.3.0 Fault Module Timestamp: 585a1a7e
This isn't an issue with UAC since I've moved my install elsewhere, I know that much, but beyond there I don't think I can solve this issue on my own; I'm definitely not the kind of guy to go rooting around inside usvfs_x86.dll and know what I'm seeing.
