This error message is from the ASO driver (Advanced Software Option) for an ISA board.
ASO was originally for Windows 3.1 and 16bit compilers such as VB3.0 or MSVC++ 1.5.
To use ASO with 32bit compilers such as VB4 or MSVC++ 4 (or higher), you need to have both the original 16bit ASO driver and the 32bit patch or update files installed. The 32bit update files are available by download as a driver update for your board. The file name is asowin95.exe.
