Game build crashes on other computers

I’m new to Unity; I’ve been learning how it works and writing simple programs. Everything worked fine until I decided to build and run a program. It works fine on the machine with Unity installed, but it crashes immediately on two other computers.

The crash error is 0xc0000005. I tried for hours to find an answer online, but haven’t found anything exactly like my problem.

Here’s a little more info:

  • I tried to pinpoint something wrong with the program, but it doesn’t seem to be the cause. Even a program composed of a single, empty scene with no objects crashes the exact same way.
  • I had the problem in Unity 2018.2.8f1, but it seemed to happen in two previous versions, too.
  • Uninstalling and reinstalling Unity didn’t help. Disabling the initial resolution selection screen did nothing, too.
  • The games crash immediately, before “made with Unity” even has a chance to happen.
  • I copied all the folders associated with the build, not just the .exe file.
  • The builds are for Windows, I tried both 32-bit and 64-bit builds on the two computers where the games crash, the effect is the same.

I have no idea where to even begin looking for an answer. I hope someone can at least point me in the right direction. I honestly don’t even know the right questions to ask - I’m completely new to Unity and have very limited knowledge of programming otherwise.

OK, so there wasn’t an issue with Unity or my computer after all. The portable drive was doing something to the files (which I accidentally discovered after a .zip file moved through it was rendered unopenable).

Sharing the build by other means worked just fine.
