I will gladly contribute a tutorial on Excel RTD, if and when I can ever get the Sterling Excel RTD Add-in to activate in Excel 2010 on my PC. So far everything I've tried, with much help from Sterling tech support, has failed. My machine must be cursed!

I will start a new thread on this issue, since it appears to be unrelated to this thread's original issue (installing .Net 1.1 on Win 7).

Thanks for everyone's help.
