Whenever I try to run older versions of Vanilla Minecraft it won't allow me to create or load a world in Singleplayer. If I try, it will start to generate the world, then crash.

Error Message:

---- Minecraft Crash Report ----
// Oh - I know what I did wrong!

Is this a system problem, is there a problem with my system settings that would cause this error? If so, what steps can be done to correct it. If not, what could be the problem?

    Can you define "older versions"? I see you are trying to run 1.7.2 here, but does this happen for 1.7.X in general? In particular, what about 1.7.4 and higher? Also, what about 1.6.X? – MrLemon Feb 2 '16 at 9:45
  • Try to delegate this profile to custom directory, something like .minecraft/customprofile1.7 , in settings of that profile. This is so important for using Forge, because other versions, vanilla and Forge could collide in files used, so there might be similar problem. Your new versions can collide with this old version, with custom directory you can be sure that this profile cannot use files from other versions. – Antoine Hejlík Feb 2 '16 at 13:38
  • It doesn't work for anything lower than 1.7.10, but someone helped me fix it. Thank you. – Nateleach32100 Feb 5 '16 at 20:02

This is an issue that occurs when downgrading from Minecraft 1.8 or higher without deleting your options.txt file or correcting its renderDistance entry. You can fix this by either deleting the file or changing renderDistance to 12 or lower. To do this, first open the game directory of the profile as described in this picture (sourced from here).

Opening the profile's directory

After that, find the options.txt file and either delete it or open the file in a text editor and change the line that starts with renderDistance to something like renderDistance:12. It can be lower, but don't increase it beyond 12. Save the file and launch Minecraft, and it should start.
