I use armory to hold my bitcoin (I have to change that...) and need to have bitcoincore maintaining the database behind.
When I installed bitcoinabc (in a different folder) it seems to have corrupted my btc database.
I had to delete and download everything again...ouch!
Can I install both on the same computer?
They have nothing to do with each other, so they should not conflict. We have run up to 100 different coins on the same box at the same time, the only issue there would be power and bogging the system. As long as ports do not conflict and you are not using two deep Java built coins, then there is never an issue.
The default datadirs do conflict (or they did when I used them) as above stated. The solution is to make a 1 line bat file just pointing out where the data is stored.
Don't try to do fancy stuff with the config logs as they both try to listen to the same log also.
