Can't open my old catalog after installing trial version
I have a perpetual licence for Lightroom 6. I thought I'd check to see if there were any updates for it and accidentally clicked the wrong button and instead clicked the Update button that installed the trial version of 8.5. So I deleted that. I still had my LR6 but it now won't open my catalog, even though I made sure that I was trying to open the old catalog file that I had restored from my backup drive. The strange thing is that my Lightroom about screen used to say version 7.0.1 or similar instead of version 6. It now says version 6.14. So I think that when I originally installed my perpetual licence Lightroom 6 two years ago, it actually installed something that had a different version number on it, even though it was just the standalone perpetual licenced software. So it must have been just the version 6 software, but was reporting itself as version 7 for some strange reason. After the trial install and subsequent uninstall, it now says 6.14 and that's probably why it won't open my catalogue.
