Excavator v1.2 is not at all compatible with Excavator v1.1 included in Awesome Miner. They completely redesigned both the API and command line options between v1.1 and v1.2, so they are not compatible at all.
At some point I will add support for Excavator v1.2, once they keep the API more stable. There will be quite an implementation effort to support the new v1.2, and so far I don't think this miner has been so popular. Also, as you probably noticed in their license information, I'm explicitly forbidden to automatically download Excavator from Awesome Miner. So the user experience will not be as good when I move to v1.2.
Agree. I am more confused about the 'show/no-show' of custom software in profit profiles... similar issue to
CPU mining with profit switching in AM dev 3.2.2)
Q: How do I set up CPU mining with profit switching in AM?
All predefined mining software (incl. CPU miner in latest v3.2.3) and all Managed Software with Full Compatibility will be listed as available for the profit switcher in the Profit Profiles.
Excavator v1.2 cannot be used at the moment, because it's not yet supported by Awesome Miner
