os x 1014: IMSlib not found

Question

After reinstalling acrobat dc, i got this error-message:
IMSlib not found. Arcobat DC doesn't work.

the only solutions that seem to to work are for windows, but i run os x.

Apparently the first cases occurred as early as 2015 and there is still no easy solution to fix it.

i don't want to uninstall the complete acc, i need up to two days to set up photoshop, indesign and illustrator again.

OS X 10.14.6

restart your computer (don't skip this)

if you're unable to install the cc desktop app at this stage, use an administrator account (solution 4 here, https://helpx.adobe.com/creative-cloud/kb/creative-cloud-missing-damaged.html)

use the desktop app to install your cc programs/trials
