I think some other people have seen this but I'm not aware of a final conclusion or complete answer. Some have suggested it appears to be a problem with the Cadence installation that happens on multiple versions.
Are you using 64bit mode? You may be successful with 32bit mode in this case.
One thing I think is interesting... the error message refers to "auCore.cxt" but I wonder if there is a typo somewhere... was it supposed to be "auCore.txt" instead? Does a file with a similar name exist at that path?
The first time I ran into this problem, I was a bit puzzled. I was not using the 64bit mode and yet it was looking into the 64bit folder for the auCore.ctx.
I looked around and found the auCore.cxt at the following location: "/tools/cds5141usr5/tools.lnx86/dfII/etc/context/"
but not in the 64 bit folder:"/tools/cds5141usr5/tools.lnx86/dfII/etc/context/64bit/" where it is looking for.
I am tempted to just copied it and see what happens.
Thank you for your time.
