If the licence number is not entered within the 60 days after installation, then the expiry message you are running into would be the result. The check occurs when first trying to load a database, so you are correct that trying to open adagio.ssi would be the time this would happen. Some files get updated after licencing the program is complete.

You mentioned that installation was done through Windows XP, which will work just fine. But WinXP has security where things installed by one user may not be seen if you log into the machine as a new user. Which login into the workstation was used when Crystal Reports for Adagio was installed? Administrator or someone else? If you log in as Admin, does this work?

From the Windows Start menu, there should be a folder specific to Crystal Reports for Adagio and an option called 'Register and Reprint Registration form'. If you do not see this then it lends to the theory that Windows security is at fault. If you do see it, then you will get the Continue / Register / License / Cancel screen. From here you can attempt to re-enter the license number that has been provided you.

You may have to reinstall Crystal Reports while logged in as the user of the machine, and re-enter the registration or license information, in case Windows security is preventing files from being accessed.
