If you have been having trouble opening jpg attachments in Quality Center and getting a shell32.dll error, we found at least one answer.

QC uses the program paint to open these attachments and if your PC ( like mine) did not have paint installed, you would get the shell32.dll error. JPG's on my pc are associated to win fax viewer and open fine but QC has it hard coded somewhere to use Paint.

Once we added paint to my installed programs, my problem was solved. Much better answer than from support ( unistall anti-virus)

Hope this helps someone as this forum has been a great help to me on other issues.
