I found the solution for the "An installation support file could not be installed catastrophic failure" problem. There was an InstallShield folder leftover from a previous VisiLogic installation that was forcing this error. To get around this, go to Program Files(x86) > InstallShield Installation Information. Search thru the folders there until you find the one associated with VisiLogic. I made a folder elsewhere and moved the files to it. I was afraid to delete it until I was sure I had the right one. I was then able to install the latest version of VisiLogic without any problems at all. I hope this info might help someone else encountering the same problem.
