Please use the version suitable for your computer and operating system, since each release downloads its own version of the compilers. The 32-bit version of UGBASIC-IDE can work with both 32-bit and 64-bit Microsoft Windows, while the 64-bit works only with 64-bit Microsoft Windows.

The software was compiled under Windows 10, and it should work fine with older versions of Windows as long as you download the complete edition (the one with .NET embedded). The version without .NET embedded requires .NET version 8.0.
