The SoftGrid Client could not launch (APPNAME)
This application has failed to start because the
application configuration is incorrect.
Reinstalling the application may fix this problem.
Error code: XXXXXX-0060922C-800736B1
then you might want to consider installing the Visual Studio Runtime Executables. It solved a problem for me where a package streamed ok, but the application itself simply refused to launch (Adobe Reader 8).
