Today I found an interesting App-V Publishing Error on a Windows 10 Device. Right now the only Supported App-V Client Version on a Windows 10 Device is 5.1 as stated in the following TechNet Article: App-V 5.1 Supported Configurations
There is one little gotcha here, if you use an App-V 5.1 Client on a Windows 10 Device and you are still running a Management Server that has not been upgraded to Version 5.1 yet. The App-V 5.1 Client on Windows 10 Client will then bring up the following error:
Sync-AppvPublishingServer : Application Virtualization Service failed to complete requested operation.
Operation attempted: RefreshPublishingServer.
Windows Error: 0x801901F4
The above error occurs because the App-V Management Server, which is still running on Version 5.0, doesn’t know how to serve a Windows 10 Operating System.
In fact, Microsoft describes this behavior in the following TechNet Article: Release Notes for App-V 5.1
An error is generated during publishing refresh when synchronizing packages from the App-V 5.0 SP3 management server to an App-V 5.1 client on Windows 10. This error occurs because the App-V 5.0 SP3 server does not understand the Windows 10 operating system that is specified in the publishing URL. The issue is fixed for App-V 5.1 publishing server, but is not backported to versions of App-V 5.0 SP3 or earlier.
As soon as you upgrade your Management Server to Version 5.1, the publishing process on Windows 10 will be successful.
I will write a dedicated blog post about how to upgrade your existing 5.0 Management / Publishing Server to Version 5.1 in the near future.
Thank you all for reading!
