The Runtime Error 5 will occur when a user executes an Invalid Procedure. The procedure is not specific to any portion of the software and usually has to do with the way the data is being entered or how the software user is moving around the software. These errors are difficult to re-create so in order to resolve, a copy of the data is needed as well as a list of exact commands/clicks that the user has done in order to generate this error.
Please contact support for further help with this error.
