Hi

SITUATION... Two Excel version 11.0 and 12.0 are installed on a subset of
machines... Depending on the last update made, one or the other is declared
as the default Excel to be launch...

This can be seen in the following registry key...
HKEY_CLASSES_ROOT\Excel.Application\CurVer that can equal
to Excel.Application.12
or to Excel.Application.11

Manifestly, only a reregistration of a given excel version can reestablish
an expected situation such as havin version 12.0 being the default one...

QUESTION...
How can I run a "LIGHT" Reregistration of Excel 12.0 through a script
launched at login time ? and this without being forced to run an Office
reparation...
Is this possible through some registry key manipulations ?

Thanks for your help
Regards
Alain
