BACKGROUND

I have Windows 10 on Microsoft Surface Pro X laptop (ARM processor) which runs Windows 64-bit but runs apps under 32-bit emulation (unless specific ARM version available).

I have CC subscription which installed/managed 32-bit version of Adobe apps. Looks like latest version it automatically updated to was CC 4.9.0.504.

REPRO STEPS FOR CC 32/64-bit FAILURES

1. I received notification that Photoshop for ARM (beta) was available and wanted to install it... --> it requires CC latest version 5.3.5.518 before I can access that version of Photoshop.
2. Manually installed CC latest version 5.3.5.518 (since CC auto-update seems to have kept me on the older version of CC, probably because it "knew" I need to keep using 32-bit version of the apps)
3. Installed Photoshop ARM Beta and verified it worked fine --> BUT CC no longer was able to "see" and manage my Adobe 32-bit apps which were installed on my computer and which I needed access to. This latest version of CC only shows Photoshop (and I think Lightroom) as being available to install as desktop apps. Obviously, this is not viable for me....
4. Went back to install older CC CC 4.9.0.504 --> This took out Photoshop ARM beta (sigh...) but restored ability to see/manage my other Adobe 32-bit apps
5. But now I have a lingering BIG ISSUE. My Adobe Acrobat DC is no longer working at all even though it is one of the few Adobe apps that is still made available in both 32-bit and 64-bit

REPRO STEPS FOR ACROBAT DC FAILURE

1. From CC 4.9.0.504, uninstall Acrobat DC
2. From CC install Acrobat DC
3. Start Acrobat DC --> Note that app title bar shows Acrobat Pro DC (not sure why... I think my subscription provide Acrobat DC, not Pro version???)
4. Adobe Sign In screen pops up (even though I am signed in CC)
5. I sign in... popup goes away and a few seconds taken to load my account info
6. Then all windows close and disappear without any warning or error message
