Cause

This may happen if the DDELaunchMSICommand or LaunchMSICommand registry values under the following keys are incorrect:

For 32-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SoftGrid\4.5\Client\UserInterface

For 64-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\wow64node\Microsoft\SoftGrid\4.5\Client\UserInterface

Resolution

To resolve this issue, edit the registry key to reflect the correct execution string.

For 32-bit clients, edit HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SoftGrid\4.5\Client\UserInterface. For 64-bit clients, use HKEY_LOCAL_MACHINE\SOFTWARE\wow64node\Microsoft\SoftGrid\4.5\Client\UserInterface.

Note that Configuration Manager clients use a different string than App-V clients. If in doubt, check the value of DDELaunchCommand. If it references VappLauncher.exe, Configuration Manager integration is enabled. If it references sfttray.exe, the client is an App-V VAS client.

The correct values are:

Configuration Manager 2007 clients with virtualization support enabled:

Value: DDELaunchMSICommand

Type: REG_SZ

Data: @GcbJDuU`8Dt4ql_+RSRVirtualApp>=T+i$+PP-9,9v}Si8@4X /launch "<APP>"

Value: LaunchMSICommand

Type: REG_SZ

Data: @GcbJDuU`8Dt4ql_+RSRVirtualApp>=T+i$+PP-9,9v}Si8@4X /launch "<APP>"

App-V VAS clients:

Value: DDELaunchMSICommand

Type: REG_SZ

Data: 3OqYobt01?4VH[gf8qiBRelease_Merge_Modules>OO5hSGuIH?xoVn&wQ(Ex "<APP>" <DDE>

Value: LaunchMSICommand

Type: REG_SZ

Data: 3OqYobt01?4VH[gf8qiBRelease_Windows_Desktops>gNkKPt-'NA05f@sdSnKH /launch "<APP>"
