Set default program for extension after msi installation

Question

Is there proper and working way to make extensions .mp3 default program with .msi installation? (I am using Advanced Installer).

So far I have tried:

Changing registry in Advanced installer for HKCU, HKLM, HKCR keys however it seems not to be working.

For example - I change those key values to my application but once I open mp3 file, registry automatically restores back to default. Why?

I had WMP11 as default, then I change it even manually with hand to my application, but then when i run my file, I press refresh on registry and it is WMP11 again.

I have tried using Advanced Installer built in solution - file associations. I filled up all required details and set it as my default program. But nothing works.

When I enter settings in Windows, I can see my application but it is inactive as default. I have to press and select it as default. But I need this to be done automatically since i will run my msi file with command line msiexec /i "myapp.msi" /qb and I dont need any user interaction..

Please help with ideas and let me know what is the proper way to do this.

Thanks a lot.

Are you on Windows 10? Some important changes have been included in it, as you can read in the linked article.

Here is an extras from the article:

We know your defaults matter to you. With Windows 10, all apps – both Classic Windows apps and Universal Windows apps – will be unable to invoke a prompt to change your defaults, only Windows. You remain in full control of your default experiences, while reducing some of the unwanted noise that multiple prompts can bring.
