In rare cases, the Iron Speed Designer installer can hang on the first step (preparing to install). Sometimes your processor takes up 100% of the CPU for an extended period of time during the first step.
The InstallShield support knowledge base recommends that you disconnect your Internet connection and try installing again.
Step 1: Download the full installer from Iron Speed’s website (www.ironspeed.com/download) onto your local disk.
Step 2: Disconnect your machine from the Internet. You can go to your Control Panel, Network Connections and temporarily disconnect the LAN adapter.
