I was trying to test VSC 5.0x6 and couldn't get the windows service to start after install. After a few uninstalls/reinstalls and diving into the logs it appears the x6 installer doesn't create the SSL keystore so the following two files are missing:
C:\Program Files\NetApp\Virtual Storage Console\etc\keystore.properties
C:\Program Files\NetApp\Virtual Storage Console\etc\nvpf.keystore
The service fails to start when it can't find them. The x1 beta creates them just fine. Grabbing them from the x1 install, uninstalling, installing x6 and putting them in place works fine. So looks to be just an issue with the installer on a fresh install. This was all on 2008 R2 Std.
