Hi, John,
We no longer do testing on really old software versions. We haven't published that Adagio Inventory is compatible with Windows 2000 since before IC8.1A(20090217).
You'll find that we do publish this information in a Compatibility topic available from within a module (select Help, Readme from the menu), from a link provided within the install and within the product's release notes available on our website. We also have a Compatibility link on our website's home page wherein we publish current compatibility with various operating systems. Select the Windows 2000 link on that page and you will immediately find that we state, "The Windows 2000 workstation will no longer be a supported platform for Adagio in future releases (any release after January 1, 2009)". Here is a link to that page:
http://www.softrak.com/products/compatibility/compatibility.phpHow you want to proceed now will probably depend on if your data has already been converted to the new version or not, and if you're willing to upgrade that PC to a more current Windows operating system. Currently, Adagio supports Windows XP, Vista and Windows 7. You may want to discuss options with your Adagio consultant.
