Decided to perform a Server Recovery. After 30 minutes of preparation and downloading, an error message: "recovery does not support this operating system" or something alike. Oups! I knew it could not install from the original disks in a x64, grrhh... forgot that. Time for a iso file so we can burn a Server Recovery Disk with WHS PP1 and HP MSS 1.3.
Plugged in another laptop an lets restart. Recovery went well. I let HP 1.3 install automatically. When server was accessible, I directly checked the Home Sever Connector Software\oem directory. There was oem.msi but no oem_x64.msi. So it did not install from the French upgrade of MSS 1.3. Then I installed PP1 through the automatic upgrade.
What else can I do? Wait for a futher release of the upgrade? Complain to HP (I don't know where)? Return my MSS?
Anyway, what am I missing here besides the MSS Control Center? Is it worth all the fuss?
