Warning "Application cannot perform an operation. Problem Firefox (17.0.1) or Windows 7?

At the start of Firefox (17.0.1), I get the message "application was unable to complete an operation."

Is this an error in Firefox or the operating system (Windows 7, 64-bit)? After that I closed the warning, Firefox seems to work normally.

Thanks for the workaround. Run Admin has solved the problem for the Version 17.0.1. The warning message does not appear for 18.0.1 - not so far.
