Lightroom Classic crash after system restore

[Ubaya]

Last month I try to update my Lightroom Classic CC and I dont know why it became expired. I used corporate lisence for CC 2018. So I use System Restore on my Windows to go back before I update my Lightroom and it became always crash when I try to open. Can someone help me?

The Lightroom programs are not known for getting along with restore. You will probably have to reinstall

And you should probably use the Adobe CC cleanup tool first, to remove all vestages of old coding and junk

And you probably should run a regustey maintance app as well.

Now by stating CC 2018, are you refering to Lightroom Classic v7?

Not a standalone version?

You will also probably need to uninstall your Adobe Creative Cloud Desktop App, then download a fresh new copy and install it afesh.
