I use Outlook Express on WXP with SP3. I'd been trying different email clients that associated .eml files with them, and eventually used folder options to change the association back to OE. At first, the files opened normally, but after a short while the entire program started loading instead of the file. If I associate .eml files with the other email client still on my computer, it works fine. Why this is happening, and how do I fix it?
Possibly there is a missing parameter in the registry and just only application starts, not the clicked .eml files. The exact commandline shoud be:
Default; it would be:
Notice the /eml parameter, it might be missing in your registry.
Try re-installing OE:
