I run V6 with success I have installed the latest version of your tool.
No installation problem
but in the process of updating the tool runs for more than 16 minutes
and never ends; I tried your suggestion “select” cancel but no response ..
I had to “X” the tool.
Hope it helps.
The main reason I can think of for this to happen is damaged data files. Please use this process to restore the files and try again:
Restoring your flight simulators original ATC voice files – EditVoicepack
The program should react to cancel within 5-30 seconds (it depends a bit on the step it is in – it might need to roll back some changes) so that does sound a bit strange. 16 minutes is not unrealistic though if you enabled all additional voices. It needs to generate hundreds of thousands of audio files. If your CPU load is close to 100% then it is still processing.
