I installed the WinGRASS-6.4.0-1-Setup.exe 55M from I'm using a x64. After installation, I tried opening the demoLocation but it failed and displayed the error: Execution failed: 'gproj -p'. How do I resolve it?

You may want to try the OSGeo4W version of the program, or try the WinGRASS list -- I see a listing you may have already posted there, in which case you likely don't need this post, the actual developers will give their feedback there – scw Feb 6 '11 at 9:24
Do you manage to enter GRASS anyway? if so, please run in the command line 'g.proj -p' and watch out for errors. I suspect that either the GDAL or the PROJ installation is incomplete. – markusN Feb 6 '11 at 21:31
I did not manage to enter GRASS. When I close the error message: Execution failed: 'gproj -p', the GRASS program suddenly terminates. – teamAngat Feb 7 '11 at 11:48
are you using the TclTl, WxPython or Text interface? does it fail similarly in all three without reporting further errors? – scw Feb 7 '11 at 11:55
Have you gotten this to work yet, teamAngat? – scw Feb 16 '11 at 5:53

You may want to try with a new version:
