About the issue when using only the Canada Maps DVD and its software
The Fugawi 3 software of the early to mid 2000s was designed in the era of most customers having computers operating with Windows 98 SE, Windows 2000, Windows NT 4.0, Windows XP. And the software ran reasonably well under those OS versions, was able to import the file format of Canada Maps on those DVDs.
However, by the era of Windows 8.1 and Windows 10 usage, it was apparent that various aspects of the Windows operating system had changed sufficiently that the old Fugawi 3 software and data were not viable for reliable technical support and regular usage. What few customers were running the software were doing so in upgraded computers with special modes of running the software.
Hope for continued use of the DVD's topo maps if you have Fugawi 4.5 installed
You may succeed at using the data from the DVD if you ignore the Fugawi 3 software from that Fugawi Canada Maps DVD -- do not install it at all -- and, instead, import the DVD's topo map data files using Fugawi Global Navigator 4.5 or Fugawi Marine ENC 4.5. The import is done from the menu Maps | Install Maps and Data, choosing the category of Land Maps and check marking Fugawi Format (FX4). The remainder of the install wizard should be able to import the DVD's topo map files given no other Windows or hardware issues blocking the process.
However, if you do not have a variant of Fugawi 4.5 this option is unavailable to you because Fugawi Global Navigator 4.5 and Fugawi Marine ENC 4.5 is no longer for sale.
