I'm posting on behalf of a user as I cover the IT Support for them. They had Adobe Reader and when we installed Acrobat from CC v22.003.20282 it breaks the preview of pdf's in explorer. The previewer worked fine with Reader but Acrobat now replaces Reader instead of sitting side by side with it so I cannot change the handler back to reader.
I've uninstalled and re-installed Acrobat several times with no luck. The preview in explorer works fine for other documents, just pdf's are affected.
I checked for any updates for Acrobat in CC but there were none available.
