FIX: Software package freeze/crash/won't start up

A simple fix for when a certain software package won't start up, most likely due to corrupted dot files.

If, for any reason, you try to run a program and it freezes, crashes, or just never starts, you may have some corrupt configuration files. This is a very simple fix, and this kb doc will walk you through it.

  1. Open a terminal. You can do this by going to the Applications Menu, going down to "System", and then clicking on "Terminal".
  2. Now you should type in "ls -a" into the terminal, and hit enter. This will list a lot of files in your root directory, including hidden files that start with a dot ('.').
  3. Find the directory for the program that is causing you issues. For explanation's sake, I will use NX 9.0 as an example. When looking through the files that show up after running the "ls -a" command, you should see something called ".nx90" for NX 9.0. This will be similar across many programs such as: ".vsim" for Modelsim, ".nx10" for NX 10.0, ".matlab" for Matlab, etc.
  4. Now, in the terminal, type "mv .nx90 .nx90.bak". I am still using NX 9.0 as an example, but the file you enter is program specific. This will move your config files to a backup directory.
  5. Now you should be able to run the program, which will generate new dot files and you should have no more problems.

If this does not fix the issue, do not hesitate to contact the CAE Help Desk.
