IE crashes when viewing HDX content pages after creating new XA65 published Desktop template image

I have just built a fresh new VM to be used as my Gold image for my XenApp 6.5 Published Desktop Hosts (I have other hosts which were deployed from a previous template, but over time I have not listed all of the changes I have made, so have not applied them to the previous gold template, hence my creating a new one.

The main difference is that this new host is running Rollup Pack 2. The previous host was running RP1. All of the other installed apps, hotfixes etc are identical.

On this new host, it has IE10 installed (same as on previous host). The Client side HDX rendering policies and hostfixes have all been applied (same as on previous host).

Issue is when I launch a site that has HDX content (eg if I open There is generally a flash Ad at the top of the site for the latest movie etc. When this tries to load (or if you manually try to open any flash video), the browser crashes and generates the following event:

Faulting application name: IEXPLORE.EXE, version: 10.0.9200.16686, time stamp: 0x52058cf0
Faulting module name: PseudoServerInproc2.dll, version:, time stamp: 0x503d18a1

Report Id: 2df2d957-2ff1-11e3-9edc-005056a87350

The only info I seem to be able to find says to either delete this registry key:

Which does stop the browser from crashing, however I then lose my HDX client rendering (which is not really a fix for the issue. We really need the HDX rendering as the business we are in requires us to have certain external flash content running all day.

All of the other info I have found refers to XenDesktop, which doesn't apply to me.

How about uninstalling the Rollup and see if the issue is still there ?

I could, but I don't know if that is going to Help. I need RP2.

One thing I did do was uninstall the HDX mediastream for flash - Server off the XenApp host, restarted the host. The error is gone after next login, but obviously no Flash HDX client rending.

I then install the HDX component back on the host and reboot. When I login again, IE is working fine, but still no HDX.

Its working now. After uninstalling, then reinstalling the HDX mediastream for flash Ad-on, I had to re-add the registry setting for the Psuedocontainermaxbrowserversion.

I did this, rebooted the host and it's all good again!!

Sorry need to reopen this. The issue reoccurred again the next day.
Same error details as mentioned in the original question.

It seems to be working again now. I uninstalled Citrix Receiver Enterprise V3.3 and installed V3.4 instead and it seems to have fixed the issue.
HowzattAuthor Commented:
Found the solution myself before it was posted on here
So the solution was ultimately using Receiver 3.4 or above?
