Fatal error occurred, program will now exit

[Timberflake1983]

Hi all,

I've just done a fresh install on my new M5 Max Mac Studio and all has gone well with the exception of MakeMKV. I'm running V2.0.0 and have a registered version (not beta). When I try to open an .iso I'm receiving the error "Fatal error occurred, program will now exit". This happens whether I try to open the file directly or mount it first. I've tried multiple .iso's and I've also tried opening a 4k blu ray which opened no problem.

Can anyone give me any suggestions as to what the problem might be?

For anyone else having a similar problem, it's the version. Version 2.0.0 has this problem, version 1.18.3 doesn't

I got the same problem. But how to downgrade? I can't find old version?

BULLBOYKENNELS yeah same here mate, 2.0.0 fell over on every iso I threw at it... I rolled back to 1.18.3 using the old downloads page d00zah linked and its been fine since (my registration key carried over no bother, so no need to faff about with that). I'd keep a copy of the old dmg somewhere safe too, because I reckon I'll be sat on 1.18.3 until they properly sort the next update. Also turn off any auto update thing if you've got it on, otherwise it'll probably bite you again when you least expect it.
