A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
First see if it happens in Safe Mode. Hold down the Ctrl key while launching Excel.
a) If it doesn't happen then the problem is caused by some add-in or a workbook that is loaded on startup. Disable all add-ins ( File > Options > Add-Ins ).
Move any files from your XLSTART folders (see below for how to find them).
You can then add things you need back in one at a time, restarting Excel and so discover which is causing the problem.
b) If it still happens in Safe Mode, try doing a repair from Control Panel > Programs and Features > Microsoft Office.
Files in XLSTART folders:
There are 3 possible XLSTART folders to look in.
You can check them by opening Excel, Alt+F11 to the visual basic editor, Insert > Module, paste in the following code and run the ShowXLSTARTFiles macro by putting the cursor in it and pressing F5:
Sub ShowXLSTARTFiles()
ShowFiles Application.StartupPath
If Application.AltStartupPath <> "" Then ShowFiles Application.AltStartupPath
ShowFiles Application.Path & "\XLSTART"
Debug.Print "Done"
End Sub
Sub ShowFiles(Path As String)
Dim stFile As String
stFile = Dir(Path & "\*.*")
Do Until stFile = ""
Debug.Print Path & "" & stFile
stFile = Dir()
Loop
End Sub
In the immediate window (Ctrl+G if it isn't visible) you will see listed any files in any of the 3 folders.If there are none it will just show "Done"
