If you receive the error "A different version of Lasergene is running" when you try to launch a Lasergene application, but another version of Lasergene actually isn’t running, there may be a lingering .state file from another version that needs to be deleted.
The solution is to locate and delete files named STARDM*.state, …where ‘*’ represents the version number. These files may exist in the following directories:
- Hard Drive:Library:Preferences:DNASTAR:DataManager
- Hard Drive:Users:username:Library:Preferences:DNASTAR:DataManager
If you find any of the .state files listed above, delete them. Once the files are deleted, the error should no longer appear.
Need more help with this?
