If you found problem installing VP-UML using the installer, just download the “no install” file. This file is actually an archive (zip) file that compressed all the program files needed to run VP-UML. So you can just download the “no install” file, decompress it to your computer, go to the extracted directory and execute the appropriate execution script to start VP-UML.
