@Risk Error: "ActiveX Component Can't Create Object (@RISK)"

First, make sure your Excel and Windows support your version of @RISK. If you have compatible versions of Windows and Excel: Log on to Windows as a full administrator. Re-run the installer and when prompted for Modify or Repair select Repair. If you are a textbook user: Log into the Lumivero Community and click the Submit a Case button. Provide your textbook name, and ask for the latest DTSuite8-Setup.exe. Download that installer to your desktop, right-click it and select Run as administrator. If you're prompted for Modify or Repair, select Repair. If you see a Customer Information screen during install, change "15-day trial" to "I am upgrading or reinstalling" If you have a 7.x textbook version, uninstall it in Control Panel, then do a fresh download. You will need your textbook to answer the challenge question. You'll get the 8.x textbook version automatically.
