The best place to install the Bridge Author's Template is the Office\Templates folder. You install the program by copying the file (BridgeAuthor.dot) to the folder. Please make sure that the file's name is not changed during the download of copying process; if an extension is added, remove it by renaming. Also, make sure the license file's name (BridgeTemplate.lic) is not changed.
For WORD versions prior to 2007, when you want to write something you engage the template by attaching it to a new document via the Tools Menu (Tools, Templates and Add-ins, Attach). Select BridgeAuthor from the available templates, and OK that. The functions offered by the program are distributed across the File, Edit, Insert, Format, and Tools Menus in a way that seems logical to me.
For WORD versions before 2007, the default location for the Templates folder is Program Files\Microsoft Office\Office (or Office xx)\Templates. When Office was installed, an option to change that location was available. If the option was exercised, you need to find the Templates folder. You can find the location of the templates folder via the Tools Menu in WORD. Navigate your way through Tools, Options, File Locations, User Templates.
For WORD 2007, WORD 2010, WORD 2013 and WORD 2016, life is a little more complicated. You need to place the files (BridgeAuthor.dot and the license file described below) in a trusted location; otherwise, WORD will not allow its macros to run. You can determine where the trusted locations are by clicking the Big Button, then Word Options, then Trust Center. The easiest trusted location to use is the Templates folder. For the Vista and Windows 7, 8, 8.1 and 10 operating systems, the default location is Your Username\AppData\Roaming\Microsoft\Templates. Microsoft has perversely, or perhaps merely paternalistically, chosen to hide the AppData folder by default. You need to make it visible in order to put the template and license files in the Templates folder. To unhide the folder, click on the Windows button at the lower left of the screen, then click on Computer, then Organize (in the upper left corner), then Folder and Search Options, then View, then check Show Hidden Files, Folders, and Drives. For Windows 8 or 8.1, you can get to the View tab via Control Panel, Folder Options. Then check Show Hidden Files, Folders, and Drives. For Windows 10, open Settings and type "folder options" in the search box at the upper right. Then click Change search options for files and folders, then select the View tab, wherein you will see the check-box.
When running WORD 2007 and later, you can access the Bridge Author template by using the Big Button to open a New document, then click My Templates..., and finally click on Bridge Author to attach the template to your document. All of the Bridge Author functions are available by clicking on Add-Ins.
The version of the Bridge Author's Template you download from this site has limited functionality until it is accompanied by the license. When you have purchased the personalized license, you will receive a license file that should also be installed in the Office\Templates folder. Installation of that license (simply copy it to the Templates folder) will unlock the full set of program features. The license file is called BridgeAuthor.lic. Some email programs may add an extension such as .txt to the license file; if that happens, get rid of the added extension. The license and the template must be in the same folder.
The personalized license grants you the right to run the Bridge Author's Template on your home, office, and laptop computers. You may not transfer the license to another person, nor share it with others in your organization. The price of the license is $10.95 USD. The license will have your name attached to it, and your name will appear when you engage the template.
The security settings in WORD are designed to protect the computer from unsafe macros. When the Bridge Author's Template is installed, WORD may be unhappy and warn you about the impending invasion. You can get rid of that warning by changing your security setting (via Tools, Macro, Security) to "LOW", but that is not recommended because there are evil macros out there.
If WORD reports that the template is blocked because it was downloaded from the internet, you can overcome the protectionism by right-clicking BridgeAuthor.dot, then clicking Properties at the bottom of the panel. Under the General tab, look for Security at the bottom, then click Unblock, then OK.
The better way to eliminate the warning is to tell WORD that the Bridge Author's Template is safe because it has come from a trusted source. The Bridge Author's Template has been digitally signed by David J. Weiss. How you inform WORD may vary slightly depending on your configuration. The objective is to tell WORD to trust installed templates. If you can make David J. Weiss a trusted source via Tools, Macro, Security, Trusted Publishers (or Trusted Sources), do so by typing David J. Weiss in the text box. Check "Trust all installed add-ins and templates". Then click OK, and WORD will remember that the Bridge Author's Template is OK.
After you create and save a document using the template, WORD may inform you that changes have been made to the global template, and ask if you wish to save those changes. DO NOT save those changes. (As of Version 3.74, this annoying and dangerous question was finally eliminated.) If you do, your global template, whose name is Normal.dot, will take on the properties of the Bridge Author's Template. Normal.dot is the default for all documents, and is used unless another template is specifically invoked. Normal.dot is also stored in the Office\Templates folder. The file may be hidden, which means that in order to see it listed, you need to turn on the "Show hidden files and folders" setting via Control Panel, Appearance and Personalization, Folder Options.
If you inadvertently do save those changes, don't panic. If you were smart enough to maintain a backup copy of Normal.dot in another location such as the Temp folder, simply replace the current Normal.dot with the backup copy. If you, like 95% of users, were not that clever, you can recreate your desired Normal.dot. Start a new document with File, New. Then clean out whatever is on the page that you don't want, put in your preferred customized settings (if any) and save the file. WORD will inform you that changes have been made to the global template and ask if you wish to save those changes. Respond that you do, and a new Normal.dot will be saved and used henceforth. There is an informative discussion of Normal.dot here.
