I am currently on a test environment upgrading JIRA through the recommended upgrade path. However, as I run the installer and choose upgrade.
This error pops up each time:
"Error while attempting to remove the previous installation directory. Some files may be in use. Please close all related programs and try again."
I'm not sure what files would be in use, or what I need to close down.
I've chosen the option to 'ignore' and the installation proceeds seemingly without issues but I wanted to know if there is a fix for this, and if choosing ignore might cause issues in the future. From what I can tell, the new instance is fully functional.
