Excel error window: Excel has stopped working

[MunganBrus]

Hello there. I have a problem with excel files and I am unable to find any solution
On my PC Office 2007 Professional installed. I have some excel files created in my old Office 2003. And when I am trying to load them in Office 2007, Excel shows me error window with the next message:"Excel has stopped working".
I copied corrupt files to my Laptop and they opened in mac office. So I saved them on the lap as .xlsx and tried to move it back on my PC. Some opened, but the most still do not.
Of course I tried to uninstall and install Office but no change. How can I get my files back?

Do you have any formulas or macros in your files? If not you can try to open it using WordPad or other similar program. But it works only with the data.
Have you tried open&repair command? It might fix the problem.

Also look at this discussion, it is possible that here you will find something.

Another way is uninstall all add-ins if any.
