The MD5 checksum in the Vector download-center can be used to check file integrity. If you downloaded a demo version for example, you can check if the file has reached your computer completely and unmodified.
You will need a software tool such as the Vector MD5 Calculator to perform a check. The only thing you need to do is to create an MD5 checksum for the file you downloaded and compare it with the one we provide in the download-center.
