I'm quite unsure if you selected the "'don't reboot' option" or not, but it makes sense that using converter needs restart (at least DRM conversion is based on additional virtual audio devices).

Have you installed the latest version?

With that maybe this helps: How-to-solve : Driver installation keeps asking for system reboot ? Drivers do not install properly ??

Quoted from "Picker22"

I uninstalled both versions of the Audials programs. Manually erased a bunch of files which the Microsoft unininstall didn't remove, ran 3 different registry cleaners and reinstalled the most current program.

It is back to working fine.

What a pain. I cannot get past "audials requires an additional component to be installed to continue" and I've done everything - well the limited suggestions - for uninstalling drivers and reinstalling them and still does not work. I guess its time to move to another software. And its not like I did not try the limited suggestions or spend time looking for solutions or trying everything from reinstalling drivers to reinstalling software. My experience is this software and its support suck. Others may have better luck than me but I can see there are still some that have my same problem.

From what you are saying: "I've done everything - well the limited suggestions" I am unsure whether you found and followed the - not quite limited - troubleshooting instructions the support has given for this problem, so to make sure you don't miss them:

And if you followed the linked instructions and they didn't help, you should contact the support team. They will assist in every possible way.

Hope this helps!
