This message points to another (possibly crashed) instance of the program still running invisibly in the background. Please open the Windows task manager and terminate HN.exe (or SynfirePro.exe). This should free up all locked files and resources. Another possible cause for this are insufficient access rights for the current user to write to the folder "C:\Program Files\Cognitone". Please set the access rights for this folder manually such that all users have full access to it.
