What are the system requirements for the SolverWrapper DLL?

64-bit MS Windows 32- or 64-bit MS Excel

Where should the SolverWrapper DLL be installed on my User Account?

This installer will install SolverWrapper in any location that you select. It is recommended that it be installed in C:\Users\[user name]\AppData\Local, which is the default location, in order to prevent the DLL file from being inadvertently moved or deleted after it has been registered. Moving or deleting the DLL after installation without first properly uninstalling will break any code that references the DLL, and render it unusable.

The installer will place a SolverWrapper shortcut on your Desktop to provide easy access to the installation folder, uninstaller file, readme instructions, and example resources.

What happens if I upgrade to a new version, or reinstall to a new location?

If upgrading to a new version, or re-installing with the same version but choosing a different install location, this installer will first unregister and then remove the older version.

How do I uninstall the SolverWrapper DLL from my system?

To uninstall SolverWrapper from your system, you can run the unins000.exe file in the installation directory. This unregisters the SolverWrapper DLL and removes all the original files from your system.

Once I have installed the SolverWrapper DLL, what is the quickest way to get started?

Use the SolverWrapper shortcut of your Desktop to navigate to the examples folder in the installation directory. Here you will find test modules that solve each of the optimization problems in the SOLVSAMP.XLS spreadsheet that comes with MS Excel (see readme file for more info). You can move or copy the example test modules (or the entire example directory) to another location on your system. But be sure NOT to move any other files, such as the DLL or the uninstaller file.

Open your copy of SOLVSAMP.XLS document and go to the Visual Basic Editor. Import each of test modules. Select Tools>References and scroll down the list of references until you see SolverWrapper. Click to set the checkmark and then hit OK from the References dialog. Save the file in a location of your choosing as a macro-enabled .xlsm file and then run any of the test procedures. Once the file is saved, this step will not have to be repeated.
