I’ve been using Editvoicepack now for years & never had an issue, since I’ve converted to P3D I can’t get it to work properly, it only updates a few voices with the new callsigns & voice tempo, which is really annoying. I originally thought it was because I had the free version but I have purchased it & the problem still persists. I have uninstalled & reinstalled it, moved the install folder outside of program file still with no success. This is also on Windows 10
The most likely cause of this is AIG AI Manager.
Unfortunately the developer of AIG AI Manager decided to use EditVoicepack to design an addon… that isn’t compatible with EditVoicepack.
Somewhere in the settings if AI Manager you should be able to deselect the voicepack it downloads. You can’t just delete the file as it will reinstall it. I do not know exactly where the setting is, so if you can’t find it I recommend posting in the AI Manage forum.
