IE Apps crash in App-V on Citrix

Question

We have 2 applications (Qbyte and BPC) that have IE front ends. We have virtualized these applications successfully with 4.6SP1 and they are both running in production on Windows 7 X86 and x64 with no issues. They both used to work in Citrix XenApp 6 running
on Server 2008 R2. However, they are now crashing in Citrix. The crash is an actual application crash of IE and not any kind of client crash.
I have tried disabling DEP, systematically uninstalling Citrix hotfixes that were applied in between the application working and not working, moving the box into an OU with no GPOs applied, enabling Local Interaction. I have tried sequencing on XP 32-bit, Win7
32-bit, Win7 64-bit and even built a Server 2008 R2 sequencer and sequenced on that. To date, nothing has resolved the crashing. Both applications work when installed locally - they only crash when running in App-V.
The crash details:
Problem Event Name: APPCRASH

Other IE applications work fine in App-V with no crashing.
The JVM is not generating an hs_err.log file or any other crash dump that I can detect. The last thing is that if I open the application, allow it to crash, but keep the crash window open, I can launch a second instance of the application and it does not crash.
Any help would be appreciated.
Thanks,
Darren.

Hi Darren,
Did you ever resolve this issue?
I don't have a citrix environment like you but I do have 15 terminal servers running windows 2008 r2 that are running app v client 4.6 SP2 and when an app v application runs iexplore.exe, internet explorer then crashes.
One thing does work and I wondered if you had heard of it. I noticed that the HKEY_Local_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Softgrid\4.5\SystemGuard\SecKey had no permissions set. So I set the System, and Administrators to full control, and Users to
read control (same as the key directly above in the tree) and IE stopped crashing. However, I have a new problem with this, in that after rebooting the terminal servers the keys are wiped of their permissions and I have to manually set them again. So I was wondering if
you managed to fix your issue of IE crashing and how?
Thanks
Simon
