Cant sign or save documents error 105

[Matthew29841471p1pk]

For the past two weeks I have been trying to trouble shoot two users who are unable to sign documents with a smart card certificat or save PDF documents. what I have tried so far is as follows

I have ensured they are using the most current version of Adobe Acrobat DC

I have ensured there copy is active using acrobat distiller

I have repaired installation

I have attempted to save documents as a optimized PDF recieved a cannot save error 105

I attempted to print to PDF recieved a cannot save error 105

I attempted to extract pages and save, same error

I cleared the local cache

I cleared the certificat cache

I ensured FIPS was off in registry and double checked in local policy

At this point I am not sure what else to try.

One of my coworkers figured out the solution today. 

1. open adobe

2 go to Edit > Preferences > Signatures.

1. Under Creation & Appearance , click More  and uncheck use modern user interface for signing.

1. relaunch the app and test.
