“…I am trying to install the latest version of GroupMail but keep getting an error during installation that says that ‘another instance of GroupMail is running’ and asks me to close it before continuing. I definitely closed GroupMail and have checked to make sure it is not open…”
Sometimes, elements of a software program remain open even after you close the application itself.
Solution
When this installation error appears, simply click CTRL+ALT+DEL to open the Windows Task Manager and End Task for any “GroupMail” or “Delivery Console” applications that show in the applications section of the Task Manager.
You should then be able to continue with the installation.
If you continue to have problems after doing this, contact the GroupMail Support Team.
