Please help.

[sdcardbitzz]

But I really need that version.

[sdcardbitzz]

I don't have a powerfull PC and that's the only version I can use.

Please, just help me.

You should be able to play 1.7.10 just fine if you can play 1.7.2.

Its NO major changes just bug fixes.

As for 1.8 update, it isn't that much of a performance decrease as everyone says.

Either way, 1.7.2 is not supported here as no matter what you think there is NO reason to use 1.7.2 over 1.7.10. So, Update.

[LexManos]

Ah, well, old computers are old and shouldn't be used anymore update to the last decade
