FULL DOWNLOAD -- OrchidWiz Encyclopedia X6.0
If you look at the bottom left side of your browser, you should see the file being downloaded. After the download finishes a few hours later, click DISK1.zip. It will open a new window showing the files contained inside. From that window header menu, click "Extract All" and then select "Extract." This extracts all the files from the zip file and puts them in a folder you select (the default "Downloads" folder works fine).
The default location may be called Downloads\DISK1. Open that folder and double-click Setup.exe. A window might come up saying "Windows protected your PC." Click "More info," and then click "Run anyway." That should start the installation.
If you wish to download the individual installation files, one by one, they are located here:
You will need to have all the files under the same folder in your computer before double-clicking Setup.exe to start the installation.
