App-v 5.0 Pre-cache error in VDI.

Question

Hello All, 
I have a Citrix XenDesktop VDI Pooled Desktop (nonpersistent) deployment with Microsoft App-V 5.0 full infrastructure. 
I was testing the pre-caching of my App-V 5.0 packages (%ProgramData%\App-v) as the Shared Content Store was not providing the best user experience. 
So I modified the registry setting on my client to turn off SCS, and then done a publishing refresh (using an admin account that had access to all App-V packages), this worked great. The contents of %ProgramData%\App-v changed from small 80Mb to 18
GB (same as my content store location). I loaded the App-V Client UI and clicked on packages, they all indicated packages are now avaliable offline (so 100% cache) & also running the command
Get-AppvClientPackage -All indicated that each package was PercentageLoad=100 
Before I shutdown my image and real-seal it for read-only mode, I went add and Unpublish-AppvClientPackage
(all of them, there is no easy way to do this via powershell..btw)
So, now when I launch a Virtual Desktop as an end user, the applications are not working... I am receving a ton of error indicating missing files, so I went to the environment viewer and found these throughout the logs. .. 
Content required by an application could not be retrieved from the network. A request for file C:\ProgramData\App-V\4015C3CA-1ED9-4876-8423-915CA4B2BEF0\92FAE2E7-B5FA-4DBF-A4F0-EDE27CF421C8\Root\pwsafe.exe from package version {92fae2e7-b5fa-4dbf-a4f0-ede27cf421c8}
failed with error The parameter is incorrect..  Check your network connection and try again.
Now I am not sure why it is trying to retrieve additional files, considering all my packages are now available (fully cached) in %ProgramData%\App-v.  NOTE: If I remove all packages from the image in write mode Remove-AppvClientPackage
and enable SCS the errors do not appear and all packages work perfect. 
I did not pre-publish any settings when the image was in write mode, so when my user logged on in read-only mode noticed the user environment (VFS) and start-menu creation occurred (as it took 1-2 minutes to complete), which was expected. .. .
I have google the above error, but could not find anything to help out.. Any ideas how to get precache working in VDI environment?

Answer 1

Do you re-publish the application during user logon (and how)?
When you log on to a session and call get-appvclientpackage -all - do they show the full 100% load?
BTW pre-caching all packages can be done with get-appvclientpackage -all | mount-appvclientpackage.
Similar to this get-appvclientpackage -all | unpublish-appvclientpackage should hide them all. When (un) Publishing make sure to hit the right scope. if packageas are 'published globally', the -global switch has to be added:
get-appvclientpackage -all | unpublish-appvclientpackage -global
Note that HF4 for SP2 (http://support.microsoft.com/kb/2956985/en-us) introduced new settings targeting VDI deployments, they are a little bit explained at http://technet.microsoft.com/en-us/library/dn659478.aspx
