1. Download the fixed file to a temporary location such as C:\temp
2. Find the directory where the original Sunbear 3 files were written from the original CD. Usually this would be C:\Program Files\Sunbear3
3. Navigate to that directory and rename the original executable, just in case, to something like sunbear3_84.exe
4. Copy the downloaded executable from C:\temp to the same directory found in step 2
