Is there any harm in installing an older version of Acrobat along with the new version?

Question

I'm running Acrobat v11.0.04 on my iMac. For my work, I have to create pdfs and upload them to a special server that then generates dynamic versions of them (blah blah blah... I don't really understand that part of it...). Anyway, it can't use PDFs created by this version of Acrobat... or the last few versions, for that matter. So... is there any harm in installing version 8 (which does work) on my iMac? I don't want to get rid of version 11... I want to have both.
Thanks!

Answer 1

I am not sure anyone knows what the server needs. We just know what doesn't work. What DOES work are the pdfs I compile (I have to combine two pdfs into one) are the ones created from version 8. I will ask if I can get specifications. It's confusing because I create the pdfs and send them to someone else. He uploads them to this server which is run by another company. So there are a lot of different levels involved. All I know is that every time a new version of Acrobat comes out, I create a test pdf and it doesn't work. I always have to go back to version 8. I recently bought a new computer and didn't want to install version 8... but unless we can figure out  a way to generate the "right" pdfs, it looks like I  might have to. Anyway, I'll see what I can find out.
