I have reproduced this problem ... .looks like I introduced this bug in build 64.
The new installation verification routine is changing the path from gsview32.exe to gsview.exe and so you can't see any ps files.
Until I fix it ... you have to go to Settings/PostScript and change it to gsview32.exe, save the configuration and then try viewing it.
Or, copy gsview32.exe to gsview.exe ....
