Trying to run WSUS on a laptop that is way back on updates
It is a Windows 7 home Premium Swedish 64 bit on desktop
Settings:
Windows 7 x64
Copy updates:
USB Medium C:\WSUSData Clean
Program works on downloading lots of x64 stuff
Ending wsus offline update download for w61-x64 glb

switch to C:\WSUSData
click on "Updateinstaller.exe"

"Checking user privilegies"
"Determin system properties"
"Error: Unsupported Operating system x64"
"Ending"

So I now have 2 desktops where the program does not work.
I also run it on my laptop which is a W10 Pro English. That worked

I think, it is the same problem as you posted here.
I'll suggest you, not to open two topics.
