I have Adobe Reader (9.4) and Adobe Acrobat (4.0) installed on my PC.
Windows XP is set-up to open PDF files through Adobe Reader which works fine. Then I have a software (refmanager) that opens PDF files automatically with Acrobat.
I would like to have the files opened in Reader as well. I tried all combinations of installing/deinstalling all software, but found the order of installation to be irrelevant for this problem. What I noticed is, there are two possibilities in my set-up to open PDF files with the "open with" option, namely open with Reader 9.4 and open with Portable Document Format. The former opens with Reader 9.4 as expected, the latter, however, opens with Acrobat 4.0. I suspect, refmanager opens the PDF files also through that command.
Now, how can I force Windows XP to open Portable Document Format with Adobe Reader? I already went through the registry but could not locate the problem there.
