Steve,
It appears that target machine has a problem with one of the system components, called "Windows Script", formerly known as "Windows Scripting Host". If you search our forum for "script" or "scripting", you will see that some other users had issues with this component. Usually it gets inadvertently uninstalled and since it's a system component, UltiDev Cassini installer does not look for its presence before starting installation, resulting in installation failure. In your case it looks like the component itself is installed, but got corrupted somehow. We recommend
downloading and installing the latest version of Windows Script on the target machine and then try installing UltiDev Cassini once again.
Please let us know if this has helped.
Best regards,
UltiDev Team.
