Need Lightroom Classic - installed Lightroom Desktop when upgrading from Lightroom (old) version 5

[denniss87168340]

I had to subscribe to this version of Lightroom (windows desktop ver 6.4) a year ago when I got a Canon R10 and the CR3 files were not recognized by my Lightroom 5 stand-alone that I had been using happily for a very long time.

I've had problems with this new version from the beginning, but I attributed that to my being old, slow to learn new systems, etc. I noticed that after just a few months of using this version, my laptop would slow down. It has become progressively worse, to the point where today as I was trying to edit and save photos that I took at my daughter's wedding this past week, I can't complete anything anymore. I hve no other programs running. I have tried maximizinf the cache size. I have turned the GPU off. I have seen references to catalogs and opening or closing those, but I do not see that option on the version of Lightroom that I have. I have a little over 8,000 images in folders and albums.

I have a feeling that there is something other photographers are doing, that I am NOT doing, that enable them to make Lightroom a reasonable workflow. Lightroom 5 was always faster - much faster - on my machine and I am more than disappointed. Can anyone help?

Lightroom Classic 12.4 is a direct replacement for the Lightroom 5 you were comfortable with.  Is there any reason you went with Lightroom Desktop 6.4 (Cloud-based) instead?

I had to replace my camera. I bought a Canon R10. It shoots in a different
RAW format than the previous camera, CR3. The version of lightroom I had
could not read the CR3 files. That's why I went to the version I am using
now

Lightroom Classic is what you want. It is version 12.4 - released in June 2023. It has support for your camera. You do not need to use Lightroom Desktop (6.4) to do this. They are two separate, current, up-to-date active programs and both support your camera. 

You mistakenly installed a Lightroom not suited to your needs.  Trust me, you will be a lot happier with Classic as it is an updated version of the Lightroom 5 you are used to.
