Custom instances from old launcher cannot be read by the new launcher ("inherits properties from an unknown version")
The native launcher sometimes fails to download the version JSON for an inherited version, resulting in a launch error. This works fine in the Java launcher.
To reproduce
Before reproducing, delete .minecraft/versions/1.8.6 if present (I chose 1.8.6 as it is an old, unlikely to be used version).
Then, create a folder named MCL-5443 within .minecraft/versions, and within that folder, create a file named MCL-5443.json. Put the following in the file:
{
"inheritsFrom": "1.8.6",
"id": "MCL-5443",
"time": "2017-05-13T17:52:47-07:00",
"releaseTime": "2017-05-13T17:52:47-07:00",
"type": "release",
"jar": "1.8.6"
}
Now, open the launcher, and create a new profile. Select MCL-5443 for the version. Attempt to launch that profile.
Observe that the launcher crashes (not the game, the launcher), rather than downloading the appropriate version (which it does on the Java launcher). On subsequent launches, you will receive the message "the version you are trying to play inherits properties from an unknown version".
Unfortunately, I'm not able to consistently reproduce this behavior, but it does happen. I'll keep trying and try to capture a stacktrace through VS.

Please attach the crash report. If it's not an actual game crash, but it just fails to launch, please attach a screenshot.
This may be a duplicate of MCL-5443, if the error is "inherits properties from an unknown version".
Note that bugs within modded versions are not supported here (you must contact the mod developer), only bugs within the way that the launcher launches versions (which does include mod profiles). You haven't given enough information to determine which one it is.
Thank you for your report!
However, we need additional information to diagnose this issue.
Please attach the crash report. If it's not an actual game crash, but it just fails to launch, please attach a screenshot; if the launcher crashes with a Windows "Stopped working" message, please indicate that.
This may be a duplicate of MCL-5443, if the error is "inherits properties from an unknown version", or there was a "stopped working" launcher crash. This issue has been resolved in the past by playing the vanilla version that that version is based on before playing the full version.
Note that bugs within modded versions and outdated versions (1.7.10 is several years old) are not supported here (you must contact the mod developer); only bugs within the way that the launcher launches versions (which does include mod profiles).
Can I get a copy of that custom version? There should be a json file at .minecraft/versions/your-optifine-version-here/your-optifine-version-here.json

I can't play mods like galacticraft anymore. ;(
From my experience, this seems to occur when you run a mod prior to running the vanilla version. You also have to run the vanilla version using the updated launcher, if you did it with the old one but not the new one, this happens. In addition, if you do it wrong once, the launcher sends up some sort of flag or something and the profile doesn't work any more. Here's how to fix:
1. Delete whatever profile you were using to run the mod.
2. Run the vanilla version that the mod uses. (ie. if you were running Forge 1.9.4, you would run Vanilla 1.9.4)
3. Close that.
4. Create a new profile with whatever modded version you were trying to run.
5. Run that new profile.
This should fix your problem. If it doesn't, then follow the same steps as before but delete the modded version you were using between steps 1 and 2, and then re-install the modded version between steps 3 and 4.
FYI before I post my comment
I am using the twitch desktop client for modding my Minecraft game and the game version I'm modding is 1.10.2 and tested 1.12.2 [same error in both with latest forge versions at the time]
I just tried that and it failed I also tried using the jar launcher and that also failed but it shows a unique error that is more descriptive than the native launcher
it told me that an "error occurred during initialization of VM"
that it "could not reserve enough space for
{a ram amount in kb}object heap"
{i'm using about 3-4gb as it is in the recommended scalable bar in the twitch client settings}and "Java HotSpot(TM) Client VM warning: ignoring option PermSize=256m; support was removed in 8.0"
{the perm size i am not knowledgeable in}Is this still a concern in the current Minecraft Launcher version 2.0.1003 / 2.0.1004? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.
Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. It will be reopened it as soon as the requested information has been delivered.
