MC27 and 26 Coexistance
« on: March 10, 2021, 03:25:01 am »

MC27 and MC26 should be able to coexist on the same system, but it seems that launching one immediately hangs or kills the other's process.

Is anyone else seeing this problem?

They can be installed at the same time, but running both simultaneously probably requires very careful setup, and even so might not work. Was it ever supposed to work?
- they can't open the same library (except if they're in Client mode) due to read/write file locks
- they need to use different ports, they can't be both on 52199/52200
- they probably can't both be DLNA servers (same ports, again)
- single instance setting should probably be off in both
- If the code uses the same MUTEX names across versions, then it won't work at all or will freeze while doing some operations
