SketchUp pro 2015

Hi
I have a 2015 SketchUp pro classic license. My computer crashed and was unable to transfer to my new computer. SketchUp support says-
I’m really sorry to be the bearer of bad news. I’ve checked with both my manager and a senior technical engineer, and they’ve confirmed that we no longer support SketchUp 2015, nor do we have a download for that version available. I understand this can be frustrating, and I apologize that we can’t assist further with that specific version.

Once again, you could also try asking in our community forums, https://forums.sketchup.com
It’s a fantastic place to connect with other SketchUp users who might have insights or the installer.
Anyone have the installer download or a way out of this problem. Still have my license info.
Cheers Curtis
