I had Acrobat 9 Pro and could create PDF files from Word 2010 files by going directly into Acrobat.
Then, one day, I received an error msg: "Secruty Level set to High, please run the application which created this document ..."
I figured that MS has installed some sort of security update which prevented me from creating PFD files from Word 2010 files.
So I waited for Acrobat X to ship, which I just bought for $199 (on top of the $449 for Acrobat 9 Pro).
I just installed the new version of Acrobat X Pro, but I get the same error message.
Thanks, but the error msg is actually an Acrobat msg.
I called the Adobe Tech Support and spent an hour on the phone with the gentleman. We went through many configurations and I'm still trying to resolve this issue (I'll be reinstalling Acrobat X in a minute to see if our changes make a difference).
I believe the trouble lies in the fact that I'm on a 64-bit system, with an MS-issued security update. Hard to say exactly what the fiasco is all about just now.
