Optimization with Password Protected Sheets

Evolver now allows you to perform optimizations with worksheets that have been password protected in Excel (as long as the adjustable cells specified in the model are not locked, since the objective of an optimization is to change the values of those cells).

Loading Other DecisionTools Suite Add-ins

A new menu item in the Utilities menu allows you to load other Palisade DecisionTools products from within Evolver.

Evolver Now Appears in Excel's Add-in List

You have always been allowed to add Evolver add-in (Evolver.xla) to the Excel add-ins list so it will automatically load every time Excel starts.  However, this process was difficult because it required you to browse for the correct file.  Now, Evolver will automatically appear in the add-ins list (unchecked) the first time you launch it, making it easier to access.

Language Switching Does Not Require Administrator Permissions

If you have installed more than one language version of Evolver on a machine, you can now switch the active language (via the Application Settings) even if you do not have administrator rights.

Loading Evolver and RISKOptimizer in a Single Excel Session

Evolver and RISKOptimizer can now be loaded in a single Excel session.
