Hello,

Probably, you put the chm file into wrong folder during setup?

Another possible issue: be sure that F1 pressing is handled by your handle (you can simpify display message box to be sure).

Also can be bcs of you place chm in program files - due UAC system may not allows to perform changes in Program Files folder, but chm once loading creates an chw file - try to make your application help folder in UserData, and put your chm file in there.

Regards,
Maxim.

Maybe help viewer executable is missed, are you available to open that chm file by clicking on it?
Try the next staements instead of yours:

Assembly _assembly = Assembly.GetExecutingAssembly();
string _path = Path.GetDirectoryName(_assembly.Location);
Directory.SetCurrentDirectory(_path);
Help.ShowHelp(this, _path + "\\" + "HelpFile.chm");
