Would I be able to use this to have multiple versions of Minecraft on my computer at the same time?
I upgraded to 1.0, and am loving it, but my multiplayer server of choice is still on 1.8.
So if I could run 1.8 and 1.0 at the same time I could get the best of both worlds until they update the server.
I actually got to this thread from a reddit thread where someone was looking to do the same thing as me, and this solution was suggested in the comments.
However, it seems that the above link is 1.0.
So is there a version that does this same thing with 1.8? If so, could someone please let me know, it would be much appreciated.
I was having the same problem as the OP, and after trying every solution I saw posted here, I was still getting the same error. No matter how many times I re-installed java, or uninstalled it and then installed it, or deleted Minecraft and re-installed, nothing changed.
So I got fed up, went to Control Panel, went to Programs, and uninstalled everything with Java in it's name. I then did a global search and deleted every instance of the Java folder I could find *except* for C:\Program Files\Java. I then tried launching Minecraft again, and this time got a "this program requires I Java Runtime Environment 1.50" or something, clicked ok, and was linked to the Java download page. I downloaded Java, opened Minecraft again, and almost had a heart attack when I saw that this heavy handed obliteration of Java from my computer had actually worked, and I can play Minecraft again.
I think the problem originally arose from my moving the JRE to my recently downloaded eclipse folder (as the eclipse install doesn't come with a JRE for some ridiculous reason), and, like a dumb ass, I cut it instead of copying. Later reversing this didn't help, it was only when I nuked the whole thing from orbit that it worked.
So for anyone still having this problem, and still not getting any of the solutions to work for you, just go to Control Panel, then Programs and Features, and uninstall everything Java. Then bring up the start menu, do a computer wide search, and delete everything with Java in the name except the folder C:\Programs\Java. Then open Minecraft again, and if you get an error about Runtime Environment 1.50 or something, you are on the right track, and the download it will take you to should work. If you still see the same error, try deleting that last folder too (you will be re-installing anyway), and then just to be doubly sure (and to take out some anger on Java for wasting so many hours of my day with this bs) I deleted everything out of the recylce too, so there was no trace of Java outside that one folder.
If this works for anyone else, let me know.
