A 'browser' is the software program we use to view webpages. The most commonly-used are Internet Explorer (now Microsoft Edge), Google Chrome and Mozilla's Firefox.
Browser providers have had years to make the downloading of software programs very simple and easy yet the process for many is still confusing if not overwhelming and it's complicated by attempts to protect us from malicious downloads. The frequent result is false warnings about potential download risks ('false positives').
Regardless of the browser any file being downloaded should be saved to the computer instead of run from the Internet. Doing so may make the installation more reliable and will preserve the download file for future use.
The most popular browser is Internet Explorer so let's address how it downloads a file first. Clicking on one of the red download buttons above will display a bar across the bottom of the browser screen:
Chose Save. When the download finishes, choose Run and follow the prompts to perform the installation of BCSS.
Chrome makes it more difficult to understand and follow what's happening. Unlike the previous example there is no choice bar presented. Instead, a rectangular box is displayed at the lower-left of the browser window - which quite often is not noticed because the browser window is not maxed. If it appears something is not happening, click the maximize button (to the left of the 'x' in the very upper-right corner of the browser window to display all of the browser screen. When the download completes, click on the lower-left box to start the installer:
Firefox is similar in action to Chrome but instead of a box that might not be viewable, Fire Fox uses a down arrow in the upper-right that flashes briefly to indicate that the download has begun. When the downloads completes, click on the arrow to access the installer file.
Regardless which browser is in use, when 'save' is elected or when the downloading has completed, the downloaded file can be found in the downloads folder. To access it in Windows 7/8, Click on Start then the Windows Username and select Downloads. For Windows 10 in Cortana type downloads.
In any Windows edition it's convenient to right click on the desktop away from any icon and select Properties or Personalize. In 7/8 click on Change Desktop Icons. For w10 click on Themes then Desktop Icon Settings. Check the four boxes for Computer, Recycle Bin, User's Files and Control Panel. 'Network' is optional and is handy for situations where multiple computers are connected through a local network. In the future, find the Downloads Folder by clicking on the desktop icon for Username. As an alternative, right click on the Downloads Folder then New then Shortcut and choose to place a shortcut on the Desktop.
