Removing code from a program is never a good idea if the program works fine for everybody else. You`re either missing dependencies, permission or compatibility for the program. Might be some outdated or corrupt .dll files in the download, or dependencies files on your own computer.

Could you post the code that you removed from the program?

Also, try to re-download the program, re-open it in cmd so that it outputs a command log for us to have a look at.

Nobody here can help you if you`ve tampered with the code.
