Run-time error 7 occurs when Excel is unable to find enough memory on the users system to run VBA macros, use solver, save, or do anything else that requires memory.

This usually happens when there isn't enough space on the hard drive to submit the file. It can also occur on University owned computers that limit allocated memory to students.

Your options are to:

  • Delete some things from your computer to make more room, and then try and submit again
  • Submit from a different computer
  • Send your file to MyEducator Support to be submitted by clicking your name -> contact us in MyEducator. You can also email us at, but sometimes Gmail and other email providers prevent sending Macro-enabled files.

If you have plenty of space on your computer, but are still encountering this error, please take a screenshot of the error and send the screenshot and file to our support for us to have a closer look.
