The Machine that I use for Mastercam also has a new version of Excel installed.
Mastercam X5 locked up when I tried to pick from the quick drill Tables.
My fix to the problem was as follows.
Navigate to C:\Users\Public\Documents\shared mcamx5\common\FBM and open up the file FbmToolTable.xls Then Save As FbmToolTable.xlsx (latest format) Close Excel and delete the older File.
This worked for me! I figured I go ahead and share this in case someone has that same problem.


PS: This is a Win 7 64 Machine
