Again followed your instructions to the letter.
-Uninstalled all my VC++ entries (2010, 2012, 2013)
-Uninstalled both GSX and Addon manager then re-installed them taking care to close any anti-virus programs. Again they both stalled at the VC++ installation.
-Added exclusions to anti-virus as required.
-FSX opens fine. FS2Crew opens fine, EZDok opens fine, RAAS opens fine but still no addon manager or GSX.
