Perhaps you are running into a windows compatibility "feature" -- the virtual
store <>. Older windows programs in the pre
winXP era used to write configuration files in their installation
directory. But starting with win vista, this was no longer possible by
default due to the default filesystem permissions. In order for legacy
applications to work semi-correctly, the writes to the program files folder
are redirected to a "Virtual store".

A possible workaround is to install VMD outside the program files folder
(for example in C:\VMD or something).
