Cannot start winmail on windows 7

It seems you are experiencing an issue with starting WinMail on Windows 7, potentially due to another process interfering, such as a virus scanner. Since you've uninstalled Norton, it's possible that remnants of the software or other processes are still affecting the operation of WinMail.

Here are a few steps you can take to troubleshoot this issue:

1. Check for Running Processes: Open Task Manager (Ctrl + Shift + Esc) and look for any processes related to Norton or other antivirus software that might still be running. End those processes if found.
2. Clean Up Residual Files: Sometimes, uninstallation does not remove all files. You can use a cleanup tool or manually check for leftover Norton files in the Program Files directory and remove them.
3. Perform a Clean Boot: This will help you determine if background programs are interfering with WinMail. You can do this by using the System Configuration tool (msconfig) to disable all non-Microsoft services and startup items, then restart your computer.
4. Reinstall WinMail: If the above steps do not resolve the issue, consider reinstalling WinMail or repairing it if you have that option.
5. Check for Malware: Run a full system scan using a different antivirus or anti-malware tool to ensure that no malicious software is causing the issue.

If these steps do not resolve the problem, you may need to look into specific error messages or logs that could provide more insight into what is preventing WinMail from starting.
