Questions and answers for: Windows 2000 support

Ive been using PDF24 on my Win2K server for several years, and am very happy with it. I noticed recently that PDF24 is forcing me to peform an upgrade, but then the upgrade wont work stating its not compatible with my OS. Id be happy continuing to use the old version, but it wont function at all now; only gives me the option to upgrade when I try to use it. Is there some way around this, so that I can continue using PDF24 on my Win2K box?
