Cannot install 1.5 new content

I get this message when trying to install- “The upgrade patch cannot be installed by the Windows installer service because the program to be updated may be missing or the upgrade patch may update a different version of the program. verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch.”

The 1.5 program updated OK, though.

heeeelp meeeeee. :open_mouth:
