How to troubleshoot crashing and not responding issues with Excel
Method 1: Start Excel in safe mode
Safe mode lets you safely use Excel without encountering certain startup programs. You can open Excel in safe mode by pressing and holding Ctrl while you start the program or by using the "/safe" option (that is, excel.exe /safe) when you start the program from the command line. When you run Excel in safe mode, it bypasses functionality and settings such as alternative startup location, changed toolbars, the xlstart folder, and Excel add-ins. (However, COM add-ins are excluded.)
If your issue is not resolved after you start Excel in safe mode, go to method 2.
Method 2: Investigate possible issues with COM add-ins Many developers create add-ins for Excel. These add-ins are divided into two types:
· Excel add-ins that are saved as .xla, .xlam, or .xll files.
· COM add-ins. These add-ins usually have to be installed and include DLLs and registry keys. COM add-ins created for one version of Excel frequently are incompatible with a newer version, and may cause the system to stop responding. They are not disabled by safe mode.
. add-in is causing the problem. To disable COM add-ins, follow these steps:
1. Select **File **> **Options **> Add-ins.
2. At the bottom of the dialog box, change the Manage dropdown to COM add-ins, and select Go.
3.
Clear the check box for
any enabled COM add-ins. select OK.
If disabling the COM add-ins alleviates the issue, try enabling them one at a
time to test for the problem add-in.
