Cannot access catalogue in LR Classic because it thinks it's still accessed by LR CC

[ChrisPort]

My subscription for Creative Cloud had lapsed (thought it was an automatic renewal). When I renewed it,  CC updated and because I still use Windows 7 Pro, Lightroom CC is no longer compatible. My Lightroom files are stored on a portable hard drive. When I try and open the latest catalogue in LR Classic, LR thinks it's still open in LR CC and won't let me access.

I tried opening it using LR CC on another PC which has Windows 10, but get the same message. I don't really want to change to W10 on my main PC because I have older software still in use that won't be compatible with W10.

Any suggestions?

Can you post a screenshot of the error message?

And for clarity, when you write LRCC, are you referring to LR Classic CC, LR 2015.x, or to Lightroom CC, the 1 year old cloud-dependent program?

Hi John,

LRCC = Lightroom CC the cloud-dependent version, which now requires a version of Windows 10. LR Classic CC is still compatible with Windows 7 and can open an earlier version of my catalogue but it's doesn't have any images imported after a certain date.

It looks like Lightroom crashed, or at least did not quit properly the last time. That is why you see so many temporary files as well. Look for a file called Lightroom Catalog 2016-2-2.lrcat.lock (don't confuse it with the catalog file without the .lock extension). I don't see it in the screenshot, because it's probably hidden by the error dialog. Trash it and try again.
