Hi Anney
My name is Jegan, would like to assist you regarding your request.
Try restart your computer and open excel again.
Have you copied your chart templates in any other destination?
the default location is
C:\Users<User Name>\AppData\Roaming\Microsoft\Templates
Also navigate to the File tab > Options > Save and enter the path to the templates folder in the Default personal templates location box:
You may also try run excel in safe mode.
In the Search Box above Windows icon, type "Excel.exe /safe" without quotes and enter.
File > Options > Advanced - In General section (go very much down in Advanced), check "Ignore Other applications that use Dynamic Data Exchange (DDE)". Close and re-start the Excel. Uncheck "Ignore Other applications that use Dynamic Data Exchange (DDE)". Close and re-start Excel again.
If nothing works
