Any help on this error? I get this when run the code pasted below when the output.txt file is in the correct directory. If the output.txt file is not in the correct directory, I do get the output saying Could not open file.

The problem you are having is actually caused because you have Visual C installed. Basically whenever a problem occurs it thinks it needs to debug that problem so it pops up to try and debug it. If you don't honestly need Visual C installed (if you don't do any coding in it) I would just uninstall the program and your problem should go away.
