You might find that when you are installing from floppy disks, you are required to do excessive disk swapping. It is often suggested that you restart with extensions off to solve this problem. We believe that the problem is caused by a conflict between the VISE installer and Thunder 7. This problem has been reported in ClarisWorks, FileMaker Pro, and ClarisImpact but may affect others as well.
Thunder 7 is a control panel which allows spell checking any text in any application and is manufactured by Baseline Software.
Workaround, install with extensions off.
