Momentics PE 6.2 Installation Problem

I am trying to install Momentics on my new Toshiba notebook with Windows XP
Professional. The first QNX Installer window is displayed correctly. When I
click on QNX Momentics Professional Edition, it also shows the Installshield
Wizard window correctly. But when it shows QNX Software Installation Setup
window, it losts all the text including the caption on the buttons. Can
anyone tell me what’s wrong?
