Installation stopped at 21% with the error message "Windows cannot open this program because it has been prevented by a software restriction policy. For more information, open Event Viewer or contact your system administrator".
I was able to overcome this problem by disabling Cryptoprevent.
However, at the end of the installation, I then had the second error message "Could not execute the external program
C:\PROGRA~1\AVVCS7~1.0\driver\drvinst.exe", which installs a virtual audio driver.
The program did nevertheless open, and I was able to register it. I haven't had time to check its functionality: it seems to be using up to 30%CPU even on idle on this old machine.

many thanks for this my grand kids love it when i Skype them in funny voices and it makes me look cool and that is not easy for a 63 year old man lol

i found this very easy to use but lost my main program when i moved to a laptop nice to have a ¬old friend¬ back very easy to set up and regester all working great again and called Australasia this morning and had a chat

THANK YOU

Installed and registered easily enough, but after half an hour of fiddling with it and it's difficult-to-use UI, I was unable to figure out how to translate an MP3 file to a new file with a different voice, which is the only use I have for a program like this. It seems likely it's possible to do this, but not obvious how.

Uninstalled, which also involved having to manually install the audio device driver it installs - which the uninstall program should have eliminated on its own.
