Download and Install Instructions:
Close all applications, Excel in particular, to avoid possible confusion from on-screen clutter.
There are two options to download What'sBest!
1. WB-WINDOWS-18.0.exe: This option tends to be more convenient because the files are unzipped automatically. First run WB-WINDOWS-18.0.exe.
Then, press the Unzip button to unzip the files. In order to unzip the files to a non-default folder, specify the path to that folder before pressing the unzip button.
2. WB-WINDOWS-18.0.zip: This method may be of use if anti-virus software on your computer makes it difficult to run a .exe file. The first step is unzipping the files to an arbitrary folder.
Then, open the extracted folder and run SetupInstall.exe.
