When you have downloaded this program / file and verified that it is really a Windows program and that it is compatible with your Windows, delete the file and try to download and run it again. During the download it is possible that the file was damaged or the download was not carried out correctly. If it happens again after the second download, contact the website offering the download, possibly a corrupt version of the file you are trying to download has been uploaded by mistake.
2.) The file is not intended for Windows!
Perhaps you have downloaded a MAC OS, or Linux, check that you are downloading the correct file for your operating system.
It is also the case that if the program or Windows application was developed and intended for a 64-bit (x64) version of Windows and you run it in a 32-bit (x86 / x32) version of Windows, it will not function!
3.) The file is a virus, a trojan, or other malware!
The error is not an error but a generated message that comes from the chess software! For example, if it is a virus, Trojan horse, or other malware. Check whether a virus scanner is installed on the computer that prevents the installation or execution of viruses and Trojans. Try scanning the file to make sure it is not a virus. ►►► .... virustotal.com
