WfWI.exe crashes when any of the following are attempted:
  • Dragging and dropping any new custom action onto an existing action that is in an If Statement condition.
  • Attempting to move an action (with Ctrl + up arrow or down arrow) past an existing action in an If Statement condition.
  • Attempting to cut an action and paste it into an existing If Statement condition.


Wise Package Studio
Windows Installer Editor 
MSI Script




This issue is fixed in Wise Package Studio 7 SP1 and Wise Installation Studio/Express 7.0.

There are also two workarounds available:

  1. Drag and drop new actions anywhere but onto existing, conditioned actions.
  2. Sequence the custom action using the All Custom Actions view:
    1. Select the All Custom Actions view in MSI Script.
    2. Double-click on the action that needs modified. (You can also add new actions here.)
    3. Select the Location tab.
    4. Change sequence and condition as needed.
