An optimized citrix virtual explorer published app and observations that came with it

So while back whilst working on an issue with a customer got some great feedback regards to their day to day workings – what worked well and what didn’t work for them. In particular my focus lay in particular on what their performance was like in their interactions with using office files and what they could do to improve them. My observations enclosed:

Citrix profile management users – be careful if updating your VDI to W10 branch release 1809

Recently we looked to upgrade our VDI build (1803) for EA testing to the latest branch release and encountered issues relating to citrix user profile management.

During the upgrade received the following message “error during MIGRATE_DATA operation”.

Resolution

Updating our patches on the existing build to include patch KB4343909 resolved the issue, link below :

Having trouble registering your Azure hosted XenDesktop VDA with your on-prem XD controller?

Recently was testing Azure with our on-prem solution as part of a proof of concept we were doing and noticed the VDA’s were appearing “unregistered” in Citrix Studio.

Turns out there is an additional CTX article to review –

https://support.citrix.com/article/CTX134971

Review the registry keys under the multiple forests with 2 way or 1 trusts. In particular the keys below:

  • For a 32-bit VDA: HKEY_LOCAL_MACHINE\Software\Citrix\VirtualDesktopAgent\SupportMultipleForest (REG_DWORD)
  • For a 64-bit VDA: HKEY_LOCAL_MACHINE\Software\Wow6432Node\Citrix\VirtualDesktopAgent\SupportMultipleForest (REG_DWORD)

Citrix virtual apps & desktops 7.18 and new app-v features

As outlined by Ben’s article in Citrix blogs (see: https://www.citrix.com/blogs/2018/06/15/using-app-v-dynamic-deployment-user-configuration-files-with-xenapp-7-18/ )

a key new feature that has been added and long sought after was the ability to alter the dynamic configuration files that came with your app-v package. Delighted this piece is in now as a million and one use cases for it and just wish it was part of the LTSR release which would make it even better.

Essentially in tandem with the app-v sequencing feature for install capture in AppDNA (see: https://docs.citrix.com/en-us/dna/current-release/configure/install-capture/dna-execution-profiles/dna-execution-profile-appv-51.html) this helps speed up packaging times, also provides more flexibility in the testing cycle as most times will be looking to amend the deployment files rather than that binaries within the app-v package itself.

 

Having skype audio issues using citrix published desktop in a Win10 BYOD environment?

Been getting instances of this recently with our BYOD environment relating specifically with windows 10 devices. Seems the default behavior for the later version of receivers is reverting to the light version which cuts off some functionality required to make user’s be heard on skype calls – they can hear but cannot be heard. Enclosed are steps to resolve this.

Getting “Cannot start” launching app-v published apps in Xenapp 7.x environment?

Further to an earlier post i did relating to a similar error message I did come across this issue again in 2 separate environments. Oddly v.uneven in how often it would happen but it would only occur with the app-v published applications we had.

Summary of environments

Both Xenapp 7.13

VDA’s running 7.15

Published to VDA’s running MCS and PVS images respectively.

Band-aid fix was to reset the profile in Director. Did see instances of “bad” profiles having files in their AppData\local\Microsoft\Credentials folder but a removal didn’t do anything.

Ultimately came down to controller version. Upgrading environments to the 7.15 LTSR resolved the issue. If you review the readme for 7.15 it details the fix specifically:

https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/whats-new/7-15-ltsr-initial-release-/fixed-issues.html

When launching an App-v package using the Microsoft App-V 5.0 infrastructure integrated with XenDesktop, the App-V package might fail to synchronize and the following exception occurs:
“Cannot start <applicationname>” [#LC5483]

 

Excellent post on recommendations running WS2016 in Citrix Xenapp 7.15 LTSR CU2

Shout out to Wendell who posted some great recommendations regarding the above setup – will definitely save some time for folks in the long run particularly relating to UPM configuration piece and getting that right, details enclosed:

A quick and easy way to segregate Prod/UAT/test citrix environments

Recently came across this question on the citrix discussions and must say Martin has come up with a novel approach to what could of required a more complicated solution – see thread below:
