In-place-upgrade and installation of Citrix XenDesktop/XenApp 7.8 VDA on Windows 2012 R2 fails “Ica_TS.msi”

Today I unexpectedly had a challenge upgrading a Citrix XenApp 7.6 VDA to Citrix XenDesktop 7.8 VDA on Windows 2012 R2. During the in-place-upgrade of the 7.8 VDA or a reinstallation of the 7.8 VDA, the installation fails at the section Virtual Delivery Agent:

The XenDesktop Installation log (opened if Show error log is enabled) is showing the following error:

13:20:54.8513 $ERR$ : XenDesktopSetup:Installation of MSI File 'IcaTS_x64.msi' failed with code 'InstallFailure' (1603).

13:20:54.8513 $ERR$ : XenDesktopSetup:InstallComponent: Failed to install component 'ICA for Remote Desktop Services'. Installation of MSI File 'IcaTS_x64.msi' failed with code 'InstallFailure' (1603).

13:20:54.8523 $ERR$ : XenDesktopSetup:Recording installation failure. Installation of MSI File 'IcaTS_x64.msi' failed with code 'InstallFailure' (1603).

 

The following error is in the Application log of the Windows Eventviewer:

 

Product: Citrix HDX TS (retail) -- Error 1911. Could not register type library for file C:\Program Files\Citrix\Euem\Service\SemsComLibrary.tlb. Contact your support personnel.

 

 

To solve this issue, uninstall the following Windows updates prior updating or installing the Citrix XenDesktop 7.8 VDA:

• KB3139923, https://support.microsoft.com/en-us/kb/3139923
• KB3072630, https://support.microsoft.com/en-us/kb/3072630

After the VDA upgrade/installation it is save to reinstall the KB updates again!

“Failed to launch the resource ‘XenDesktop 7.6 $S1-1’as it was not found.” After upgrade to StoreFront 3.5

This weekend I was upgrading Citrix StoreFront 2.6 to Citrix StoreFront 3.5. The in-place-upgrade was working out of the box and finishes successfully at once! When testing the upgrade by logging in with ThinClients, we cannot connect to any XenApp 7.6 resource (PubApps and PubDesktops). All the XenApp servers are in a Registerd state to the Desktop Delivery Controller. When investigating the eventviewer of the StoreFront servers I found the following Warning message: “Failed to launch the resource ‘XenDesktop 7.6 $1-1’ as it was not found”

After some investigation I’ve found out that Citrix StoreFront 3.5 cannot handle spaces and dot characters in the Display Name of Controllers. My customer has XenDesktop 7.6 as display name containing spaces and a dot:

Renaming the Delivery Controller Display name to XenDesktop solved the problem:

Attention is needed for users which have added resources in their Citrix Receiver. After renaming the Delivery Group Display name, they should add the resource again to their receiver.
