Universally available

Our software solutions work smoothly on all modern 32-bit and 64-bit Microsoft Windows versions: Windows 10 · Windows 11 · Server 2016 · Server 2019 · Server 2022.

Older Windows versions (such as Windows 8 and Server 2008) are not "officially" supported but should still work remarkably well. The underlying architecture of Windows is evolving and our apps are crafted to be backward and forward compatible.
