@Risk Error: "Object disposed."
Restart Windows. If you have RISKOptimizer in Excel's list of active add-ins, click the Go button at the bottom of the list and remove the check mark for RISKOptimizer. RISKOptimizer loads automatically when you load @RISK, but it must not be loaded directly as an Excel add-in. If you installed @RISK by double-clicking the installer: right-click the installer and selecting Run as Administrator. During the install, you'll probably see a selection Modify/Repair/Remove; select Repair. If you continue to have issues, log into the Lumivero Community Home Page and click on the Submit a Case button to fill out a form for assistance from the Support Team.
