Sorry that it’s been a while, but I’ve had my hands full. I need to do this GPO install of Spark, though, so I’ll toss something together once I get a chance. It does look as simple as copying the unpacked JAR files to an installation folder and creating shortcuts.

There… this MSI file still has one oddity where Windows Installer builds spark.ini and starter.ini with quotes around one installation path entry. I also had to redo two rows in the MSI to have the ClassPath entries put in correctly, though doing so violates Windows Logo Certification rules because the resulting strings are too long.
However, it’s complete, and Spark appears to work OK. I won’t consider this package finished until I’ve had a chance to test it more.
