I installed the office and home version 2007 from digital river site and started it as a trial. But the files were not associated. (docx, xlsx. etc wont open by office) . I activated the windows but it did not associate any office files again. Is there any simple and legal way (without virus) from microsoft office web site that I can restore the file associations? (Note: I would not use right click on a doc file and say "always open with office" because there lots of excel, word, ppt extensions and I can not do all of them one by one.
