Take the Shark email extractor available from this site. I'm using it to get email addresses from my old Outlook Express folders on my old Sony Vaio Pentium II running good ol' Windows 98 (remember that?).
Typical error message which I cannot now specify since I uninstalled everything that didn't work runs along the lines of runtime error 'line', or missing xxxxx.msi file please specify folder. When I specify the temp folder into which the setup has unzipped, nothing changes.
Why I posed the blanket question was because I suddenly re-called - or appear to have recalled - some little note in a long ago trawl around web news to the effect that email extractor programs were considered spyware. It made me wonder whether all such programs have been deliberately disabled by conscientious software distributors. Course, I could have dreamed that.
