Error message: Output file missing or unreadable

 

I’m having problems using the APBS plugin in VMD (tried both in Win XP 32 and Ubuntu). I have previously just used the pdb2pqr web service successfully but when I try to run it locally I get the “output file missing or unreadable” error message using the same pqr-file as the web server. I don’t have any spaces in the path, so what could be wrong?

 

Another weird thing is that when I Install APBS, I make C:/program/APBS the installation directory, but it always puts the executive file directly under c:/ and there is no APBS directory.
