**Note:** This is the first tutorial i have wrote, so any feedback would be welcome.

**Step 1:** Make sure you have the program you are checking installed and not running.

**Step 2:** Download and install [dotPeek](https://www.jetbrains.com/decompiler/) (Free, no signup or trials)

**Step 3:** Run dotPeek and go to file \> open and select your program.

**Step 4:** Your program will be added to the assembly explorer with .net framework version it requires (if required) or not supported if .net framework is not required.
