OS: XP Pro sp3 and completely up to date.
Acrobat 9 Pro and up to date
Just installed FM10 (+ updated) and I also uninstalled Acrobat 5.
When users go to Save As PDF it tells them they must have Distiller v5.0 or later, it fails to recognise or utilize Distiller 9..
Trying to figure out a way to get it to work w/o reinstalling Acrobat.
If you take a look at the forum threads, you'll pick up pretty quickly that SaveAs PDF isn't really a recommended way to create a PDF because it has a long history of bugs.
To debug your current situation though, have you installed the Microsoft HotFix for all PostScript printers, including Distiller? This is the baseline for any PDF work on XP systems...

After that, can you Print to the Adobe PDF printer on your system? Both from other applications and from Frame (in Frame's Print box, check Generate Acrobat Data and uncheck Print To File)?
Depending on the order of things, you may have clobbered your Pro install with the headless one that ships with FM. I suspect you should clean out all instances of Acrobat (Pro & Reader) and reinstall just Pro.
Your uninstall of Acrobat v.5 probably wasn't as clean as you thought, especially if you did his after installing FM. There are remnants pointing to the older version left over in your Registry that are confusing the FM installation. If you just used the Acrobat uninstaller, then that's virtually a certainty. Using a tool like Revo Uninstaller provides a more rigorous cleaning to the Registry and file clean-up.
Also, you could try running the Acrobat Repair option in the Help menu.
