Try installing the latest UR7 update. Yes, the fix is in a later release for UR7 and installing UR8 will not fix the issue.

The file that contains the fix can be downloaded here:https://support.microsoft.com/en-us/kb/3063263

It is the one with [.504] at the end of the version number and with the yellow contouring.
