Just click on yes to install a newest version. UFO Kirby program run on .NET framework, so if you have an old version, it can't run.
I already tried to download the version that you designed for me and I get an installation error
What version of Windows are you using?
Windows 7 ultimate
It may have incompatibilityes with .NET 4.7.2. The older versions of Kirby U.F.O worked fine?
Yes the previous versión works for me but do you have a solution?
