You’ve recently updated the Adobe Flash Player on the Citrix XenDesktop 5.6 VDI and HP Thin client t610 from 11.7.xxx.xxx to 12.0.0.77 and noticed that as soon as you use Internet Explorer 9 to browse a page with an embedded Adobe Flash video:

Internet Explorer has stopped working

A problem caused the program to stop working correctly. Please close the program.

Close the program

The following error is logged in the Application log of the VDI:

Solution

Option #1:

A search on the internet brought me to the following forum post:

http://discussions.citrix.com/topic/339058-oops-you-did-it-again-ie9-crashes-after-flash-upgrade-119900117-xa65/

… where users indicated that reverting back to 11.7.700.169 corrected the problem so I went ahead and tried reverting back to 11.7.700.272 as shown in the following screenshots:

**Note that it is important to run the uninstall executable first or you’ll receive the following error:

The installation encountered errors:

The version of Adobe Flash Player that you are trying to install is not the most current version. Please visit the Player Download Center to obtain the latest, most secure version.

Reverting the Adobe Flash Player to an earlier version stopped Internet Explorer from crashing:

Option #2:

Not being satisfied with reverting to an earlier version, I decided to test upgrading the 5.6.300 VDA agent to the latest 5.6.400 version:

… and noticed that this also fixed the issue.
