Yes, I always confirm the administrator privileges pop-up. The installation
itself seems to finish without any problems and there's plenty of disk
space. I tried executing VMD via Powershell to investigate further and
verified that the program seems to quit (maybe crashing?) right after

Output from Powershell:

PS C:\VMD> .\vmd.exe
PS C:\VMD> .\vmd.exe
PS C:\VMD> .\vmd.exe
PS C:\VMD> .\vmd.exe
PS C:\VMD> .\vmd.exe
PS C:\VMD> .\vmd.exe
PS C:\VMD> .\vmd.exe
PS C:\VMD> .\vmd.exe (yes, I needed to execute vmd 8 times to get the
output below)
Info) VMD for WIN32, version 1.9.3 (November 30, 2016)

PS C:\VMD> -- (VMD just stopped here?)

Worth noting that the warning message mentioned in the previous email only
appears sometimes (sometimes the VMD window just popup for less than a
second). Is there some conflict happening? For the record, I'm using an
Intel HD Graphics 4600 (drivers up to date).
