I distribute a Windows application written in VB 6, and i am using InstallShield to install the app on the clients systems.

A client has recently contacted me, saying that Vista will not open or display the help system that is installed along with my application. The application installs and runs fine, only the help system will not run.

The help file is compiled with VbHelpWriter compiler, and it produces a (xxx.hlp) file. I have never had any problems until this one client running Vista.

I am not sure if all versions of Vista will not recognize the .hlp file.

Can anyone shed any light on this, as well as any fixes for this ?

Would the use of a different help compiler solve this problem? (which ones are compatible with Vista?)

thanks for your help,
Robert
