I am sorry that I speak only English. The forum has a solution for this problem. A posting by "Michael" says: "For those on Windows 10 that run into problems with the installation try downloading the zip file from here. Uncompress the zipped file and click on the UFile 2021.msi file to initiate the installation. I had no problem installing and opening the program." If you translate this back to your language, it will guide you. Regards, 88keynote
