Adobe Acrobat Reader DC will not run after uninstalling Adobe Flash.
After uninstalling Adobe Flash, when I start Adobe Acrobat Reader DC I get the following error: Invalid Plugin Detected. Adobe Acrobat Reader DC will quit.
It sometimes takes 10 seconds or so for the rror to come up.
I tried re-installing Acrobat Reader DC, but had trouble here too. The regular installs from https://get.adobe.com failed with 'Install Failed', that's all it says.
I found I could install successfully using a full install file: AcroRdrDC2001320064_en_US.exe, but I still get the 'Invalid Plugin Detected' error after install.
If I deleted or renamed the following plugins from the C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\plug_ins directory that it would stop this error: EScript.api IA32.api
But now other things like 'Check for Updates' do not work.
Installed Acrobat: C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroRd32.exe Version: 20.13.20064.405839 Creation Date: 2020/10/23 Creation Time: 9:42:24 AM Locale: English (Australia) OS Manufacturer: Microsoft Corporation OS Name: Microsoft Windows 10 OS Version: 10.0.19042
Anyone can help?

Ok solved - not an Adobe problem, rather it was a Microsoft Windows one. I think uninstalling flash was just a co-incidence.
Running debug (WinDbg) showed that there was a problem with code verification for the .dll plug-in files. I discovered this was not just with Adobe but also for other install files. With debugger I get errors like:
