Could be you have 8.3 filenames disabled for 'performance reasons'. It
fits the initial case, but I'm not sure it would explain the 2nd
c:\Erlang\ scenario.

Does "pushd c:\PROGRA~1\ERL59~1.1\lib\wx-0.99.2\priv" work for you?

The other option is that you're missing some MSVC runtime dependency
for the DLL. Check with depends.exe (you'll need to google/download
it) but its self explanatory really. IIRC this error can also occur.

My final next step would be to run procexp from sysinternals.com and
get a list of all activities referring to wx in filepath. This will
likely clarify where erlang is searching and failing to find the DLL.
