Desktop Director Error: Desktop Director encountered an internal error. Please contact your IT Admin for assistance

Hi All,

I recently came arcoss the following error when I was installing Desktop Director 2.1

In the Event Viewer I found the following errors:

ISAPI Filter 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\\aspnet_filter.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a AMD64 processor architecture. The data field contains the error number. To learn more about this issue, including how to troubleshooting this kind of processor architecture mismatch error, see

Could not load all ISAPI filters for site 'DEFAULT WEB SITE'.  Therefore site startup aborted.

I tried this solution however it made no difference. They suggested to run the following commands:

cscript.exe C:\inetpub\adminscripts\adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 “false”
C:\Windows\Microsoft.NET\Framework64\v2.0.50727> aspnet_regiis.exe –i

The solution was found from this post

I changed the Enable 32-Bit Applications to True on the DesktopDirector Application Pool and the issue was resolved

Improve First Time Launch Speed Utlising RadeRun

Hi All,

I am in the process of implementing a new Citrix XenApp 6.5 solution, the solution utilises application steaming to the server and I noticed the first time launch speed was really slow.

I found this article. I had assumed I could use RadeDeploy to reduce the time it takes to boot the application for the first time.

I tested the RadeDeploy solution which did copy the package to C:\Program Files (x86)\Citrix\Deploy however, it didn't reduce the time it had taken to load for the first time. Since I am using streamed to server and my network is fast, I didn't see any change

I stumbled across the following post by David Pineda. David suggested to use RadeRun to get the application into C:\Program Files (x86)\Citrix\RadeCache, Davids solution worked.

I created a script that I run on my master image that empties and caches all of my citrix applications on the local image. The script looks somthing like this:

cd /d c:\Program Files (x86)\Citrix\Streaming Client
'Clear the applications PreDeploy
radecache /flushall; ' Flush All Applications
'PreCache All Microsoft Applications
RadeRun.exe -e /app:"Application Name" /package:"Application Profile Location\Profile.Profile"


I used the following application to get the RadeRun commands
