Tried to log in to myskom.kfib.org from my father-in-laws computer with a Windows Vista guest account. The program was placed in a folder under the account folder. After clicking connect I got the stack trace below. Sounds to me like the guest account didn't get the correct access, or the placement of the program didn't work (I have little option to place it anywhere else though, I tried the desktop without luck).

Shows some other people with this problem, but no one seems to have found a solution.
Since it works on my computer there might be something special with your installation.
Is it an "untouched" guest account, or is it locked down further by a system administrator?
