Hi mdesign, also it looks like you may have 2 sets of quotes around the c:\UpdateRhinoClipboard.exe, one pair of single quote ' characters and another pair of double quote " characters. Modify that to have just one or the other in that spot.

It works!!! Thank you Michael for your effort with solving my issue. I`ve changed single backslash to double and removed unneeded pair of quotes. It helped to solve that issue exactly as you said.

Cheers!!!

You're welcome mdesign, I'm glad that it's working now!

I have tuned up the shellExecute method for v5 so that if there was an error in launching the program it won't try to wait for it to finish.
