I've been able to properly set up a portable version of Minecraft on my school computers since last school year. Recently, Minecraft's launcher has updated and with the new launcher some computers are unable to run Minecraft. The Mojang start screen loads, and the progress bar nearly fills before crashing. When the game does crash, I get the text "java.lang.UnsatisfiedLinkError: Failed to load library: C:\Users\USER\AppData\Local\Temp\4307-75ee-89c2-ccf5\OpenAL.dll (error code = 5)" Oddly, even though every PC is identical, one of the three I have tried is able to run the game properly.
Here is the crash report, hopefully somebody knows what exactly is wrong.
