I had hoped that Parallels 7 would fix a file association problem that I am having, but no such luck. I use Adobe Acrobat to create a pdf file from multiple files of different types, including word, excel, pdf, and jpg files. In Parallels Adobe Acrobat does not recognize Word and Excel files as supported file types in Adobe Acrobat. This makes Parallels unusable in my work environment which relies heavily on the use of Adobe Acrobat to create daily pdf files from a variety of sources. Adobe works fine in a standard windows machine or in VMWare Fusion. This problem only occurs with Parallels Desktop.
