Also seems hard to believe based on these CREATED and MODIFIED dates that this latest version from the just-downloaded ZIP would actually be the very latest version of HELP for donor version 727 in August 2016. Then the CHM file should be viewable again.

This deletes the Internet zone bit of the file. Right-click on it, go to Properties and make sure that the Allow button is not displayed on the General tab or, if available, click on the button. Seems the dates must have been manually manipulated rather than set by Windows. A simple test helps to check, whether this is the cause: Just move the CHM file to a local folder. NOTE: looking at the Properties screenshot I posted above, I do find it odd that the "created date" for the file is AFTER the "modified date", with both of them being way back in January 2015. They both clearly accomplish the same result and remove the "blockage". Unblock button in right-click Properties dialog for CHM, or Streams utility from command-line. I obviously had completely forgotten about it until deciding to retrieve the latest CHM.ZIP file for donor build 727 today, and thus once again running into this issue.Īpparently either method will work, to make the HELP usable. I'm certain it was this UNBLOCK button solution I had used in the past, years ago. => I am guessing that the "unblock" button is invoking the STREAMS command (or its equivalent) on the specific file involved, for which the Properties dialog is being presented. Īnd in fact, when I went to the originally expanded version of the CHM file (from its delivery ZIP) and right-clicked on it, sure enough just as predicted there was an UNBLOCK button at the bottom of the dialog window that I could push:Īnd sure enough, after pushing the UNBLOCK button (the description area then went gray, and actually was not presented at all after closing and re-opening the right-click Properties) I was now able to fully use Help. Try the HHReg utility or read this technical note from the Microsoft Knowledge Base. This button is not available in all systems though. Right click on the file then go to its properties and click the "unblock" button.

In some cases, you can have access to an "unblock" button in the properties page of the help file. Make sure your help file isn't in a path with symbols such as "#" (sharp). Launch help file from local drive and not from a network path or via a mapped networked drive. When viewing your CHM documentation, Microsoft's HTML Help Viewer is showing an error page saying either that: Actually, this problem had seemed familiar and I was certain I'd run into it before, although I certainly didn't use Streams to resolve it.Ī bit more research shows that it has already been anticipated in the README for FCXE:
