It doesnt look like PS has the same local file permissions as other scripting options on our machines. But when I ask PS to call the VBScript I reproduce the same problem as before.
Since we’re expanding our ability to read these custom files with. VBScript has no problems opening up a brand new browser pointing to the HTML file.
