Most think-cell charts are based on Microsoft Graph. A broken Graph installation may make PowerPoint crash when think-cell tries to use Graph as usual. The cause is often an incomplete removal of previous Graph installations, possibly due to a problem in the Microsoft Office installer. To find out if you are experiencing this problem, follow these steps:
Open the VBA editor with Alt+F11. Select your workbook and click on Insert → Module. Then paste the changeSeriesName() macro, which tries to rename a series name, and run it by pressing F5:
Sub changeSeriesName() Dim oshp As Shape Dim ograph As Object Dim inserted As Boolean inserted = False For Each oshp In ActivePresentation.Slides(1).Shapes If oshp.Type = msoEmbeddedOLEObject Then If oshp.OLEFormat.ProgID Like "MSGraph*" Then inserted = True Set ograph = oshp.OLEFormat.Object ograph.Application.DataSheet.Range("01").Value = "new Name" End If End If Next oshp If inserted = False Then MsgBox "No Microsoft Graph object found. Please insert a Microsoft Graph object and try again." End If End Sub
Result: You will receive the following messages and the series name cannot be changed:
To fix the problem, manually delete the incorrect TypeLib remnants of previous Graph installations from the Windows registry.
Please contact your internal IT and ask them to perform the following steps. Manually modifying the registry may cause serious problems. Therefore, perform these steps at your own risk: We recommend to manually export the registry keys before modifying.
Delete the version keys (e.g., 1.x) for any version of Microsoft Graph that is NOT installed on your system:
