Excel files refuse to open

[Guest]

Suddenly all Excel files refuse to open

If I doubleclick on an xls file in Windows Explorer, I am getting a message
"There was a problem sending the command to the program"

Excel itself opens OK via Start-Programs, yet an attempt to open a file
using File-Open results in the file shorly flushing on the screen and then
Excel closes

Same files open well on another computer.

What can I do about it?

From the Windows Start menu, choose Run and enter

Excel.exe /regserver

This will cause Excel to start up, re-register all of its
registry keys, then quit. Now, try opening your Excel files.

Followed the instructions.
It requested Office2000 CD with SP1 which I let him have. A box poped up
shortly informing that the information is being gathered and then something
installed.

Yet now positive effect even after I rebooted the computer

Anything else?

Try Tools / Options / General / Uncheck 'Ignore Other applications' if it is
checked.

Don't know if this helps but;
Some time ago I was told (by Dave Peterson) that doing an "excel.exe
/unregserver"(no quotes and note the space) command prior to the
"regserver" command sometimes works where the "regserver" doesn't appear
to work on its own.

Just a thought, but having twigged that you are using 2000, try deleting your
*.xlb file. This is the toolbar customisation file and all customisations will
be lost if you do though. This file often caused problems in 2000 that would
close it down.

Thank you everybody.
It turned out that Access took similar posture.
So I've just uninstalled the whole Office 2000 and re-installed.
So far it's OK, touch wood.
Lookes like a virus?
