Bug #63711	Access to the path 'util.pyc' is denied after down grading version

Version:	5.2.35 CE Rev 7915	OS:	Windows (Windows 7)
Assigned to:		CPU Architecture:	Any

Description:
I uninstalled 5.2.36 because it was crashing to often.  I rebooted and re-installed 5.2.35.  Nothing else was running.  As soon as the installation completed, I got this error:

Access to the path 'C:\Program Files (x86)\MySQL\MySQL Workbench 5.2 CE\python\lib\ctypes\util.pyc' is denied

I checked and the file exists, and I can open the file in notepad, (yes it is binary, but it shows the file can be opened.)

Exception = System.UnauthorizedAccessException
Message = Access to the path 'C:\Program Files (x86)\MySQL\MySQL Workbench 5.2 CE\python\lib\ctypes\util.pyc' is denied.
FullText = System.UnauthorizedAccessException: Access to the path 'C:\Program Files (x86)\MySQL\MySQL Workbench 5.2 CE\python\lib\ctypes\util.pyc' is denied.

How to repeat:
Any time I try to open workbench I get the error.  I may need to try to go back to 5.2.36.  Please let me know if there is a work around.  I may try uninstalling all of MySQL, including the database engine, in case that helps.  I did upgrade the database to the current version, when I upgraded workbench.

This is a duplicate of bug #62709. If you can not upgrade to 5.2.36, please, run Workbench as Administrator.

I uninstalled workbench, deleted the 'MySQL Workbench 5.2 CE' folder, which still had files in it.  Then I rebooted, and reinstalled 5.2.35.  It seems to work OK now.
