As of a few snapshots ago, Novetus has full Windows XP support!

Some caveats though:

  - If you have errors while using Novetus install KB2468871 from the _redist directory.
    - NOTE: ReShade will not function and will result in a "K32EnumProcessModules" error.
    - You will have to install .NET 2.0 SP2 for the ROBLOX Script Generator to function.

The launcher design has also been changed to be a lot cleaner, however there will be a launch option to launch the Novetus launcher in the pre 1.2 layout

You know what, I like the concept of this Novetus thing. I see how it's like a old ROBLOX thingy, I like it. I givve you a thumbs up. Keep on going!

Yep it does, quite well actually

I hosted my own test server using windows server 2003 and joined it on XP

says its not a valid win32 file
