My site posts an HTML Help (.chm) file for our app. For most users it works fine, but I've had a couple of reports that when they open the downloaded file, all the topics are empty! This happens persistently for these particular users, even if they try downloading again.

When these same users download and install our app's Setup program, which installs the exact same .chm file, the Setup-installed .chm file works correctly.

I don't have a repro case (nor any files submitted with the reports) to compare the downloaded files against each other.

Has anyone heard of a downloaded .chm problem

I've been given a probable answer: On some Windows clients, security settings cause this. The user has to open the file's Security Properties and "unblock" it.
