I just installed my rhino 5.0 and now when I try to open the program it keeps saying there was a problem communicating with"_mcneel._zoo5", please contact your system administrator for assistance. What should I do next to solve this problem.

Did you just "accidentally" check "use Zoo" during the install process, or were you actually intending to use the Zoo as a license manager (not logical for a single user install)?  If it's the first, below are instructions to fix it:

I checked the option to use the Zoo when I installed Rhino, and I don't use the Zoo
  • On Windows Vista or Windows 7, delete all the files in: C:\ProgramData\McNeel\Rhinoceros\5.0\License Manager\Licenses.
  • On Windows XP delete all the files in: C:\Documents and Settings\All Users\Application Data\McNeel\Rhinoceros\5.0\License Manager\Licenses
  1. Restart Rhino.
  2. Enter your key when asked.

Note: On some systems, instead of the “\All Users\” folder, the path may be your “\Domain\” log in name.

Let us know if this solves the problem.
