Hi RMelmoth,
Windows 7 Ultimate may not contain Service Pack 1. It depends on how long ago you purchased it and when the disk was created.
-
Go to the Start menu and type ‘dxdiag’ into the search bar.
-
Once opened, select ‘Save All Info’.
-
Open that file and see if Service Pack 1 is listed.
-
If it is not listed, you will need to download it before the Launcher or editor will install.
Cheers,
TJ
