SketchUp Pro 2018 installation, invalid serial # & authorization code error

Hi, trying to install & use my Classic license ver. 2018.
I corrected the internet connection issue but now can’t add license & authorization code.

Is it possible you are actually trying to install the license for 2017 or 2019 instead of 2018? @colin could probably look up your license info and tell you.

BTW, please correct your forum profile. It shows you are using 2017 Make.

I will send a message to you to make sure you’re using the right license details.

Thank you

You should remove that image. Everyone can use it now to authorize SketchUp 2018.

Again, please correct your forum profile.

I had found your license, and sent the message to you.

I’m getting ahead of myself here. Not used to using this forum.
Thank you.

Sorry, I cannot find that image to delete.

I expect Colin took care of that for you.

Now click on the B in the blue circle at the top right of the forum page. Click on the person icon and then Preferences and Profile. Update your forum profile and scroll to the bottom of the page to save the changes.

Thank you. Version 2020 Classic

installed without issue.

So you’re not using SketchUp 2018 after all.

Done. Thank you for your assistance today.


I was able to look up the 2018 license, and see that it had been updated (to 2019 and then 2020). That was the main reason for the original 2018 problem.
