Typically, this error is caused by a corrupted Excel workbook, often due to problematic VBA code saved within it. In order to resolve this issue, you need to force a recompilation of the VBA project. One method is to add a new reference in the Visual Basic Editor (VBE), then save, close, and reopen the workbook. If this resolves the issue, you can usually remove the reference you added and save the workbook again.

To access the Visual Basic Editor, you can either use the menu options (1) and (2) or alternatively, press <ALT> + <F11>.

Solution 1

  1. Open the Visual Basic Editor.
  2. Go to Tools > References.
  3. Check the box for “AccessibilityCplAdmin 1.0 Type Library” or any other unchecked library, then click OK and close the VBE.
  4. Save the workbook and restart Excel.

Solution 2

Essentially, the solution requires forcing a recompilation of the VBA project. For instance, you can start by adding a new reference through Tools > References in the Visual Basic Editor. Afterward, save, close, and reopen the workbook. If this resolves the issue, you can typically remove the reference you added and save the workbook again.

Sub Example_SyntaxError
	If x = 10 Then
		MsgBox "x is 10"
End Sub

Runtime Errors
They occur while the code is running, often due to invalid operations or unexpected conditions. For example: Division by Zero; Attempting to divide a number by zero or File Not Found;Trying to open a file that does not exist.

Sub Example_RuntimeError
	 Dim result As Double
	  result = 100 / 0 ' This will throw an error
End Sub

Sub Example_TypeMismatch
	 Dim result As Integer
     result = "Hello" ' This will throw an error
End Sub

Object Required
They occur when trying to use an object that hasn’t been set or is missing. For example: Attempting to use an object that hasn’t been instantiated.

Sub Example_ObjectRequired
      Dim ws As Worksheet
       ws.Range("A1").Value = "Hello" ' The worksheet object is not set, Add: Set ws = ThisWorkbook.Sheets("Sheet1")
End Sub

Subscript Out of Range
They occur when attempting to access an element of a collection or array using an index that does not exist. For example: Accessing a non-existent element in an array or worksheet.

Sub Example_SubscriptOutofRange
	 Sheets("NonExistentSheet").Activate  'Sheet does not exist
End Sub

Overflow Error
They occur when a calculation results in a number that is too large or too small for the data type. For example: Storing a number that exceeds the limits of an integer variable.

Sub Example_OverflowError

     largeNumber = 50000 * 50000 ' Exceeds the limit for Integer
End Sub
