You don't say what the older and newer versions are so adjust the 2002 and
2007 to suit.

Since 2007 has decided it wants to be the default, de-register 2007 and
re-register 2002

Close Excel first and On the Windows Taskbar

StartRun "C:\yourpathto2007\excel.exe" /unregserver

See the space between exe and /unregserver.

Then register 2002

StartRun "C:\yourpathto2002\excel.exe" /regserver

This process should make Excel 2002 the default for opening files.

You may not have to unregister 2007 first but I err on the side of
caution<g

I have an older version of Excel I have been using. Bought a new laptop and
installed it. When I got a new version of Excel spreadsheet in an email, the
trial version of the new software that was loaded by Toshiba popped up and
took over as default Excel version. I can still use the old version through
direct loading, but everytime I click on the file in the email or windows
explorer a new version takes over )with mandatory warning about the expiry of
the trial period. How do I get the old Excel to be default again?
