After upgrading a Microsoft App-V server, client machines may receive 0A-20000194 errors when trying to launch applications

Symptoms

Consider the following scenario:

1.  You install the App-v 4.x server and set the packageroot (content directory) to an alternate location (not the default).
2.  You delete the included Default Application, package and content from the disk.
3.  You upgrade the server to a newer version of App-V.

After completing the steps above, when clients attempt to stream a virtualized application they receive one of the following errors:

A network error occurred error :  XXXXXXXX-XXXXXXXX-20000194

or

The package requested could not be found in the system data store or the files associated with this package could not be found on the server.  Report the following error code to your System Administrator.

Error code: xxxxxxx-xxxxxx0A-20000194

Cause

This is caused by an invalid value for SOFTGRID_CONTENT_DIR in the registry.

Resolution

To resolve this issue complete the following steps:

1.  Start RegEdit

2.  Navigate to the following key:

32-bit Management Server: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SoftGrid\4.5\Server

64-bit Management Server: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\SoftGrid\4.5\Server

3. Set the SOFTGRID_CONTENT_DIR value to the proper content directory location.

4.  Restart the server.

More Information

During the server upgrade, the installer first searches for the defaultapp.sft file location. After getting the defaultapp.sft file path, the installer then gets the content directory path from the SOFTGRID_CONTENT_DIR registry key. If the defaultapp.sft file path is not the same as SOFTGRID_CONTENT_DIR registry entry, the installer overrides the value of SOFTGRID_CONTENT_DIR. If there is no defaultapp.sft file (i.e. it has been deleted), the installer overrides the value of SOFTGRID_CONTENT_DIR anyway with the default installation content directory (PROGRAM_FILES\Microsoft System Center App Virt Management Server\App Virt Management Server\Content).
