Hello all,

Immediately after I installed Matlab 6.5 on my computer, I started
having problems with Excel. When I double click on the Excel shortcut,
I get the message "This program has performed an illegal operation and
will be shut down. If this problem persists, contact the program
vendor. I have no option but to reboot the machine after getting this
message.

Details:
EXCEL caused a general protection fault

I have tried uninstalling Matlab, uninstalling Microsoft Suite and
reinstalling it and various other combinations. Nothing seems to work.
I am not able to use Excel at all.

Please help. Thanks in advance.

You may need to delve into the registry too.

Start by uninstalling both MatLab and Office. Then reinstall Office. If Excel
doesn't work, uninstall Office again and use REGEDIT to find and delete
everything you can having to do with MatLab, but NOT Office. Reinstall Office
again. Does Excel work? If not, time to back up all data files, format your C:
drive and reinstall everything. If Excel does work, uninstall Office yet again.
Install MatLab first, then install Office yet again. Does Excel work? If so,
then you need to check that MatLab works. If Excel doesn't work, time to call
MatLab support. Given what they charge, you should have free installation
support, and they should be able to figure out how Excel and Matlab can coexist
on the same PC.

Can you provide me with instructions on how I can delete everything
having to do with MatLab. How can I identify which files are associated
with MatLab? Is it possible to make a back-up of the registry so that
if I delete something that is important, I can easily restore it? Thnx.

If you have Windows XP hopefulyl you can just do a restore
to a previous day before you installed matlab.

I never backup my registry so I dont know how. I assume
there are instructions on Google.com of how to "Backup
Registry" Maybe even a utility. After that I would go to
run and type in regedit. Then start off with typing in
the name of the matlab exe file or matlab itself in the
registry find. Then delete all keys that have those names
referenced. Be very careful and make sure that what your
deleting says the name of matlab exe or matlab itself.
You might want to call their tech support and see what
other names you can do a search for IF they cant help you
without having to go in the registry.

Any problem I have ever had like you are describing has
always been resolved by simply deleting all registry keys
that have the name of the program causing the conflict,
exe name of the program, or the company name that makes
the program. Be careful if you do decide to delete things
with the company name, that there are not other programs
installed on your PC that are manufactured by the same
company. This could cause additional problems.

Also have you tried searching in Google for the same error
you are having. Google web search is good at things like
that.
