When I try to boot my various Photoshop apps, Lightroom, and Acrobat DC on my desktop Mac Retina computer (5K late 2014) running on Catalina, a blank white box appears and hangs on the screen (see pic). This occured after I purchased a new Macbook Pro and migrated my apps from my older Macbook Air to the new laptop. I've read elsewere here that this is a problem with activation due to the Adobe apps being on too many computers (3), so I unistalled all my Adobe apps on the older Macbook Air. That didn't solve the problem. I can't find any information on the Adobe website where to deregister a computer, but I assumed that uninstalling the apps from my older Macbook Air would do that. Photoshop 2020 works on my new laptop, however, Lightroom does not open. I'm in the middle of a project and am really in a pickle. Can't figure how or where to chat with Adobe staff. So any help from the community be appreciated.

Update your Creative Cloud Desktop App.
Thanks for responding, Kevein. Much appreicated. My CC app is up to date. Phil

When you say "migrated" did you reinstall the apps or copy over from a backup or other means? That never works reliably.
Uninstall. Then install the CC app, sign in, and install the apps from there.
You don't need to de-register any more with CC. You can sign in and out of the CC app and will be prompted to do so if you attempt to sign in on a third computer.
Thanks, Jane, Much appreciated. When I try to unistall CC, a dialogue box appears that says I cannot do that, because I have apps on the comuputer that rely on it. Do I need to uninstall all my Adobe apps? Cheers. Phil
Oh no, that wont work correctly.
As Jane said uninstall - if you get the error message go to Activity Monitor and terminate any Adobe processes.
If that still doesn't work - run the CC Cleaner Tool (link below) then install fresh.
Hi Kevin, Thanks for you help -- again so much appreciated. I've now done everything recommended above, but it hasn't solved the problem. Indeed, if I download a new Adobe app like Rush using the refreshed CC, that has not perviously been on my computer, the same problem crops up. That big big white empty fat box appears and when closed, the app closes. This occurs across all my Adobe apps on my 5K Retina Mac (2014) running Catalina OS. I need to get advice with someone from Adobe but don't know how to access those folks -- am having difficulty finding an access point here. Any suggestions from anyone? Thanks. Phil
I was able to correct the problem by uninstalling all my Adobe apps, and then reinstalling. In the case of Acrobat Pro DC, that white box finally filled with the option to deregister my old Macbook Air laptop, which I did. That corrected the problem for Acrobat. In the case of Lightroom and Photoshop, they just started working again, with no white boxes appearing. However, I was unable to find or download Photoshop 2020 or Photoshop 2019, which I had been using previously. Don't know why. Thanks all for your help!

You're welcome, Philip. You should be able to download PS 2020 from the CC app. Click the ellipses to the right of Photoshop, then choose "Other Versions". https://helpx.adobe.com/download-install/using/install-previous-version.html
For PS 2019 you can get a direct download from here: https://prodesigntools.com/adobe-cc-2019-direct-download-links.html
