What OS do you work on?
When do you get this message?
Do you experience this with other PDF' too?
Are you running an app called Solid PDF To Word? If so that had no connection to Acrobat Pro and is not an Afobe Product. Acrobat Pro can convert, please let us know the version you have if you can't find this as an option under Save As...
OS is Server 2012 R2 Datacenter.
We get the message right after selecting the save as file location for the new file type.
This happens with all PDF's. I've tried many different sizes of pdf's.
We do not have Solid PDF installed.
