Acrobat User Community Forums

Dear Expert.
I think this issue was posted already, but I couldn't find it.
Having Acrobat 6.0 and Reader 7.0, the pdf file in IE 7.0 and OE 6.0 opens with Acrobat 6.0, not Reader 7.0. I installed Acrobat 6.0 first, and Reader 7.0 later. When installing the Reader 7.0, I selected the Reader to open the files. Tried any solutions under IE and Reader preferences, but no success. Am I doing something wrong? Please alow me your kind answer.
