I am currently trying to install the most recent upgrade of Adagio Ledger version 8.1A (2007.09.23) and during installation, I am receiving the message--"The version of Adagio Ledger in the selected directory below is too old for this service pack." My selected directory is c:\softrak\alwin. My current version is 8.0D (061013) which appears to be the most recent version. I have installed many other upgrades and have not had this problem before. What am I doing wrong????

With thanks
Cheryl
