Tracktion 2 won't work and won't (re) install - HELP!

[SuitcaseOfLizards]

I'd be willing to bet your rewire DLL is write-protected, so that when you try a reinstall the OS won't let it get over-written, thus producing the warning. If you can fire Tracktion up and everything looks/works fine, it's not worth stressing over.

As long as you're up and running, it's all good!
