The standard fixes for this problem.......

ToolsOptionsGeneral uncheck "Ignore other Applications"
Exit Excel and try again

If this doesn't work try to re-register Excel

Close Excel first and
On the Windows Taskbar

1) StartRun "excel.exe /unregserver"(no quotes)OK.
2) StartRun "excel.exe /regserver"(no quotes)OK.
See the space between exe and /regserver

You might have to designate a full path to excel.exe.
In that case StartRun "C:\yourpath\excel.exe /regserver"(no quotes)OK.

One more thing to try if any of the above brings no joy.........

Go to StartSettingsFolderOptionsFile Types. Scroll down to MS Excel
Worksheet. Then if running Win98 OS Edit select "Open" and Edit.

If using WinXP OS you would scroll down to .XLS then "Advanced"OpenEdit.

In Command line the path should be similar to this....

"C:\PROGRAM FILES\MICROSOFT OFFICE\OFFICE\EXCEL.EXE" /e (delete the <sp/e if
you want Book1 to open.

You must have the double quotes.

Below have "use DDE" checked and this in the DDE message box....[open("%1")]

Application should read "Excel"(no quotes)

Your other program errors will have to be addressed elsewhere. I suggest

microsoft.public.windowsxp.general

I have just installed SP2 and various other updates. It may or may not be a
coincidence that when I start Excel XP I now get an error box. It reads
"Files\Microsoft.xls could not be found" Despite this error box Excel does
open and works OK.



Does anyone know how to cure this please?



I also get errors opening Access, Internet Explorer and various
non-Microsoft programs.
