My guess is that you are not doing anything wrong. It may be that some
setting is not correct in your registry to allow Outlook and Snapview.exe to
work together correctly. Are you able to open the .snp file if you first save
it from the e-mail message to some folder on your hard drive?
Have you tried a different .snp file, just to rule out possible corruption
in the Sales030408_030908.snp file?
