Installer did not install backgrounds to Extra folder among other things.

I updated to the latest yesterday. The installer somehow still thinks I have Adobe Lightroom Classic. Now we all know how ugly uninstalls work. 99% of the time some junk is left behind - thus I used Revo Uninstaller to get rid of those things.

This has never caused an issue. The ON1 update however ran into all kinds of errors claiming it had found Lightroom (no option to intervene and say skip that) but not the folders and such. The installer finished and the software appears to be working.

Today I noticed that the backgrounds folder in the extras folder (under Programdata --> ON1) and now I am wondering what else might be missing.

Any ideas?
