I have been unable to open up MS Excel 2013 from the start menu.
When the option is selected I get the rings waiting icon and then nothing happens.
I.e. The excel splash screen fails to appear.
When I have tried to open an Excel file from my documents I get the error message attached.
Other applications do not appear to be affected.
I Have tried to open MS Excel in Safe mode and have been unsuccessful in opening Excel.
(A number of forums had suggested looking at add-ins via safe mode)
I have been running a Dell Inspiron Laptop with Office 2013 installed on a Windows 7 platform for over a year now - up till now without any issues. Windows updates have been kept up to date on the machine.
Trust this helps.
