Error When Starting MasterVision

On some newer computers, you can get an error message along the lines of "this program has performed an illegal operation" right when MasterVision is started. You can ignore this error and MasterVision will start normally. On Windows NT, you may get an error that says "Divide By Zero" and MasterVision will quit.

To solve both of these programs download the EslUp.EXE file below. Save this file to your MasterVision directory (c:\mv). After downloading, select Start > Run from the Windows Menu. Enter c:\mv\ESLUp.EXE and press enter. Follow the installation prompts. MasterVision should not be running when doing this. The problem should be fixed at this point. Start MasterVision and see if the problem went away.
