Plesk for Windows does NOT auto update, the feature is entierly not implemented.
What you do it Download plesk for Windows from the Parallels website, and run the installer, I upgraded today from 9.0.1 to 9.2.1
Sounds like it went smoothly (Did not check yet), but the update from 8.6 to 9.0.1 went smooth that is for sure
As for this update, the setup file (About 600MB) can be extracted if you open it with 7ZIP
So, My PLESK 9.0.1 comes with .NET 2.0 Version 2.0.50727.0 is what PLESK reports, Installing .NET 3.5 SP1 and the KB959209 did not bump that from within PLESK.
So maybe with IIS i can assign 3.5 ?
Well, i am just setting up this server so i don’t know how plesk works in this regard yet, But i sure will very very soon.
As you may well know 3.5 is an upgrade to 2.0, it is not really different at the core, it is just a larger 2.0
I will let you know as soon as i do about how this thing works, for now i have to go finish setting up this thing to use MS SQL Express edition 2008.
