Also looking for an EN version of Sketchup Pro 2018 after losing mine in a similar situation.
The screenshot link doesn’t seem to help. Can I retrieve the license key somehow?
Thanks
Mel
Unfortunately the linked source no longer offers SketchUp 2018 for download. There is no official source for it anymore. I suppose a Google search might turn up a source for it but if you find one keep in mind downloading it is at your own risk. Be aware that the web based services like Add Location, Extension Warehouse, and 3D Warehouse do not support that old version and the web browser used by SketchUp 2018 hasn’t had any security updates for years.
@colin might be able to help you with the license key and serial number if you can find the installer.
You were entitled to an upgrade to SketchUp 2019, I will message you the license details. You will still have the problem of finding a download for the disk image file for SketchUp 2019.
