HHActiveX.dll is being overwritten by a different, earlier version...

Jan 17, 2012 10:20 AM

Here's an interesting problem:

On some systems on which my .chm file for a local help system is installed, HHActiveX.dll (the 32-bit one supplied with RH9 for redistribution) is being overwritten using a different, earlier version. It is not yet clear when the overwrite occurs, but it is being looked into.

Has anyone seen this before? I don't see how it's possible that it's a problem with the .dll or the .chm, so I suspect something is awry in Windows (XP, SP3 in this case).

Thanks in advance!

Hi Burtin

I might imagine that could occur if someone installed another application that uses RoboHelp created CHM files and requires the dll.

Has that by chance been the case here?

Another possibility would be if for some reason a system restore point has been set and reverted back to.

Just some thoguhts from the edge... Rick

Thanks, Rick.

No applications were installed after the update in which my local help .chm and the .dll were pushed out to the systems in question. No system restorations occurred on any of the systems afterward, either.
I do know, though, that when my local help system was pushed out to the systems (which had the prior release of my local help .chm and the .dll), the new .dll overwrote the older (registered) one (i.e., the .dll was not deregistered and reregistered) since the path remained exactly the same. I have already suggested deregistering and reregistering the .dll.

Any other thoughts?

As it turns out, a separate, incremental update of one of the applications was pushed out afterward, and it overwrote the newer .dll with the older .dll.
So...it seems that a change to configuration management is in the works now...

Thanks for your help, Rick.

LOL, amazing, isn't it? How often that it turns out to be the case that indeed some process we were unaware of was the culprit?

Glad the mystery is solved! Rick
