Why do I get "dasshl32.dll not found" error measage?

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.
