I´m developing an Excel application that will be used by hundreds of users
from Excel 97 to 2007. I´d appreciate some help in 2 issues. If someone could
indicate an technical document/site/forum, it would be great.

1) how to manage macro enabling issues for non advanced users. Most of them
can´t run the macros for security reasons and don´t know how to change macro
security levels, etc.

2) is it better to generate an application for each Excel version and
instruct the user to install the corresponding file of his/her version or
only one application of Excel 97 that is going to run in every case?

Thanks

Ed
