Hi there!
If you would like to get assistance with trying Cassini to run on your system, please let us know. If you look at the Windows Event Viewer (Application), you may see error entries related to UltiDev Cassini. See what they say and
search our forum - you may well be able to find the solution.
If you would rather uninstall it, you may use
MSI Cleanup Utility that removes products failing to uninstall.
Best regards,
UltiDev Team.
