I have three computers on my network
One is a laptop
All are signed in to the same microsoft account
I need to be able to run sketchup on all three at the same time
I know I can install and run on two computers
I know I will have to pay for for the third computer
Adding a seat didn’t work
Deauthorizing all devices didn’t work
Third computer keeps complaining about too many activations
Any recommendations will be most appreciated
What version of SketchUp are you using? What operating system? Surely you aren’t still using Windows 8.1.
You would have to sign out of SketchUp on at least one device to be able to sign in on another.
If you must be able to run SketchUp on three machines or if you have multiple users, you should look at a multi-seat license. A standard single user subscription isn’t really suitable for multiple users, anyway.
