The Mad Virtualizer at Microsoft

When Softgrid evolved into App-V for version 4.5, the reporting model was changed to where reporting is cached by the client and uploaded to the server during DC Refresh rather than with each application launch.

While 4.5 and 4.6 clients can connect to and use a 4.1 Softgrid Virtual Application Server, reporting will be disabled due to the difference in models. The 4.5/4.6 clients will cache this information in an XML file labled by a <GUID.>

The location of this <GUID>.XML file is registered using the LastCacheFile registry value in the following registry path:

HKEY_LOCAL_MACHINE\Software\Microsoft\Softgrid\4.5\Client\Reporting

This LastCacheFile contains both the path and GUID file name.

Here is an example of the reporting cache file:

<REPORT_DATA_CACHE><APP_RECORDS><APP_RECORD Name=”Adobe Reader 9.0″ Ver=”1.0″ Server=”app-v-ms.steveth.local” User=”STEVETH\Gladiator” “Launched=”8/19/2010 8:55:52 PM” Shutdown=”8/19/2010 8:56:00 PM”/><APP_RECORD name=”Adobe Reader 9.0″ Ver=”1.0″  Server=”app-v-ms.STEVETH.local” User=”STEVETH\Gladiator” Launched=”8/19/2010 8:58:58 PM” Shutdown=”8/19/2010 9:00:19 PM”/></APP_RECORDS></REPORT_DATA_CACHE>

The server reporting tag is located in the following registry path:

HKEY_LOCAL_MACHINE\Software\Microsoft\Softgrid\4.5\Client\DC Server\<SERVER>

The DWORD value is 1 by default when using a 4.5 or later server. it can be set to 0 to disable reporting. However, if the server is 4.1 and the client is 4.5 or later, then this value will always be reset to 0.

This process happens upon detection of the App-V 4.5 or later server. An event in the client log is also logged when this happens.
