Last week I updated the software to 1.60.0.1800 on two computers, one running XP Professional and the other Windows 7 Premium, installs went fine and both versions are functioning. The difference that I've since noticed is that the database version on the Windows 7 PC has been updating over the last week and the XP machine tells me that I have the lastest database version (v2011.12.28.03) when I check for updates. Have no idea why this is happening, I've cleaned, removed and reinstalled on the XP PC but still get the same result which is no update available?
