Get "No argument found for format '%s'" error when launching or starting Toad. (83103)

User clicks on Toad icon presented in Citrix. Toad doesn't launch or start and gets the following two error messages:

"No argument for format '%s'."

Followed by:

"Toad has encountered an unexpected error. Be sure that you have full read and write access to you user profile directory and to HKEY_CURRENT_USER\Software."

Change the EXECUTE IN directory, which you can get to by right clicking on the Toad shortcut and selecting Properties.

Remove the dynamic %username% and change to a static directory path as like:

Execute in: to "u:\scripts\user\xyz"
