Get an error every time while installaing one of theese 3.

Other instruments worked fine!

While installing its stopping and get error "The feature you are trying to use in on a network resource that is unavailable."

Use Source "C:\Users\...\AppData\Local\Temp\mgxf6b8xylj\product\"

but there is nothing in that folder?!

EDIT: The Problem was there were some regedit still from an older install of theese Vitas.

Solution: Go into Regedit and search for "vita", delete the Folders from the Vitas you have problems to install.
