I found out today that Vista does not support 32-bit HLP files. Microsoft has now posted a download-fix for Vista users, but that does not help anyone who is distributing a VB6 app and does not know what version of Windows the end user has. I use Inno to create my SETUP files.
This is not a big problem right now, but it is only going to grow.
I also asked this question in the OS/Windows area, but I thought that developers in this topic area might have figured a work-around.
Thanks for any help.
