Fixing Startup problems

Unfortunately, many Excel users sometimes start experiencing startup problems with their Excel: File not found errors, compile errors, GPF's, Excel refusing to load, etcetera.

This is a list of things-to-try when Excel exhibits (startup) problems.

Errors when Excel starts

Try opening Excel without any addins or hidden workbooks

Use the Automation switch to start Excel without loading addins or workbooks from the XLSTART folder:

Click Start, Run,
"C:\Program Files\Microsoft Office\Office\Excel.exe" /Automation

Quotes mandatory, Note you may have to change the path.

If your error disappears, either an add-in or a (hidden) workbook that is loaded upon Excel's start bothers you.

Locate the offending file using the following steps:

Excel Add-ins.

1. Tools, Add-ins
2. note which are checked
3. Uncheck all (but one)
4. Restart XL
5. If no error, check the next one and repeat from step 4
    

Got the error? uncheck the one you last checked.

Com Addins

Another type of addins are COM addins.

1. Rightclick a commandbar and choose customise
2. Click the commands tab
3. Find an entry in the tools section called "COM addins"
4. Drag to any toolbar or menu
5. Close customise dialog and click that menu item
6. Uncheck all shown COM addins

If your problem still persist, some COM addins are not shown in the userinterface and can only be unloaded from the registry. Check the registry, at this location:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Excel\AddIns\

Warning: Backup your registry before making ANY changes!!!

Not an add-in? It will be a (hidden) workbook then.

Check workbooks that load at startup.

1. Find your XLSTART folder (On WIndows XP it may be a path like this:
   C:\Documents and Settings\Username\Application Data\Microsoft\Excel\XLSTART
2. Move all files out of it;
3. Open them one by one (in Excel) and find the one with the error;
4. Move the others back.

Repeat the above for the folder listed in Tools, Options, General, "Alternate Startup file location" or "At startup, open all Files in:" (The text depends on your version of Excel).

Open Excel in Safe mode

Start, Run,
"C:\Program Files\Microsoft Office\Office\Excel.exe" /Safe

The safe switch ensures Excel starts without opening any addins or using your menu customisations. If this works, chances are that your toolbar customisation file is corrupt. Locate all files with extension .xlb and rename the extension(s) to something like .old
Now try and start Excel again.

Files will not open from explorer

Reregister Excel with Windows

Start, Run,
"C:\Program Files\Microsoft Office\Office\Excel.exe" /Regserver

This generally fixes trouble with opening Excel files from the desktop or by (double)clicking them in Explorer.

Ignore other applications

Check in Tools, Options, General tab whether "Ignore other applications" is set. Uncheck it.

Trouble caused by antivirus software

NAV has shown to cause "Excel caused an invalid page
fault in module VBE6.DLL".
You might try disabling the Office plug in of NAV.

Trouble caused by corrupt temporary files

Try cleaning your TEMP folder:

In Windows 95/98 and ME

Delete all files in C:\Windows\Temp

In Windows NT/2000/XP

Find and Select C:\Documents and Settings\<user>\local settings\temp
and delete all files in there.
When a workbook contains controls from Excel's control toolbox temporary files are created in that folder. If such a temporary file is somehow corrupted it may prevent the workbook it belongs to from working normally and sometimes even causes Excel to crash.

Tip: Select Start, run and type %temp% and hit OK to directly open your temp folder.

Disabled files

Excel XP and 2003 have some new features, which may disable certain files when Excel thought them to be the cause of a crash.

If you have had a problem with opening a file, Excel may have labeled it as suspect.
In Excel, select Help | About Microsoft Excel.
Click the button near the bottom labeled "Disabled Items..."

If the offending file is listed, select it and click Enable. The file you just enabled may of course cause Excel to crash again, click here to find some pointers on how to open corrupt Excel files.
