Creo NC, "can't access list of available post processors, exiting"

[JK_13790480]

Hello, I receive the errror message listed in subject line when trying to post an NC file.  I have set the "ncpost_type" setting in the configuration editor previously.  I am using Creo 9.   Any help is appreciated.

I don't know what other settings you have in your config.pro file, but these are my settings.

If I had to guess I'd say you are either not specifying a directory for the gpostpp_dir setting, or the location specified does not exist, or the directory specified is unreadable or empty. Maybe your setting points to a previous Creo installation directory that no longer exists?

There seem to be a bunch of "default" posts (Located in C:\Program Files\PTC\Creo 9.0.9.0\Common Files\x86e_win64\gpost on my machine) provided in the Creo installation. I don't know if they are any good - I've had my own locally stored list of posts for decades.

My gpostpp_dir setting was indeed not pointing to the right directory.  It turned out that the gpost directory was missing entirely.  After reinstalling Creo and setting the gpostpp, all seems to work now.  Thank you.
