Separate Windows Installer Registry Entries for JACK and ASIO

[pljones]

What is the current behaviour and why should it be changed?

Currently the JACK and ASIO Jamulus installers for Windows share a registry key. This is not optimal where both versions are wanted as updates and uninstalls "get confused".

Describe possible approaches

• We could keep things as they are now
• We could add subkeys for JACK and ASIO
• We could use separate keys for JACK and ASIO

For migration from the current approach, I think separate keys is probably easier although subkeys is probably the technically better approach.

Has this feature been discussed and generally agreed?

One of my off-topic ramblings kicked this off.

If subkeys are doable, we should use them.

It is more than just the registry. If you want ASIO and Jack versions to co-exist on one system, you will need also to either give them different app names or else have them install by default into different sub-directories too.

The install directory is up to the user. The default suggestion can be the same, in my view. Once the user has set up once, the defaults for each install will be what they've chosen anyway.

The tricky bit is the cut over from the old registry entries to the new. Because of this, I think I'll propose dropping this from 3.12.0 (at least, moving back to Triage for now).

Ok. Since 4.0 can break compatibility with older versions, I think we can delay this to Jamulus 4.
