Hi to all.

I use with our Excel 2003 a calendar to pick a date.
Excel run without any issue for a long time........

Now we make an upgrade in our office from 2003 to 2010....
when i try to run the same Excel file with the calendar from Excel 2010 they show me "Could not load an object because it is not available on this machine"

I would like to know if anyone over here has use THE SAME calendar in excel 2003 and 2010......

PS: What can i do in my case if i need the same calendar in both versions

Thanks and regards......
