I sure wish someone would answer you, I'm having the same problem! windows 7 prof, 64bit. it was working fine to convert to pdf, then just stopped one day & gave me this message. all the other searching on the web gives no info. please let me know if you find a solution!
Since there were no answers, I will take a stab at a reponse. For the 2nd method, I suspect you could simply select the print or press job options to get the desired results or turn off "use local fonts" in Acrobat. If you check the font list, the fonts are probably not embedded and that is likely the problem.
I noticed that you have both Reader and Acrobat installed and that might cause some conflict, but should not be the issue here. If you were to uninstall Reader, you would have to repair Acrobat. The conflict here is that you might have problems with the one opening when you want the other. If it works for you, then don't worry about it.
For technique 1, I suspect you may be using IE 9 that has apparently been a problem since it came out. I have refused to install it. However, it may simply be that PDF Maker does not work correctly with your browser, or got deactivated and needs to be allowed to run in your browser (IE I am assuming).
Thank you! I'll try this- will take me a week or 2 as I'm in the middle of
writing a paper, but I'll let you know.
