Fix For Error HHC6003 (itircl.dll) 
Updated June 8, 2000

One of the most annoying problems in HTML Help is an error message which states "HHC6003: The file itircl.dll has not been registered correctly". I had brought this to Ralph Walden's attention sometime in 1998, and he said to have the individual re-register itcc.dll on the system, as there is some interaction that needs to occur between the two files that isn't occurring. Since then, I've assisted about a dozen people with this problem in this manner, explaining what Ralph told me.

One thing that's quite interesting is that, in some cases, itcc.dll isn't even on the system. I've brought this to the HTML Help development team's attention, and while I was told they've heard of the problem, they've yet to be able to duplicate it. Also, up until recently, every time I've heard of the problem, the system's been running NT. However, I've received an email about someone who had to use this fix on a Win98 SE system (thanks, Stuart!), so this is no longer true.

Ok, on to the fix:

Look for itcc.dll on your system. If it's there, register it using:

regsvr32 c:\windows\system\itcc.dll

Make sure you substitute the correct path for the location of itcc.dll on your system.

However, if itcc.dll is not on the system at all, you can download a copy by clicking here (it's about 75k zipped). Unzip it to either c:\windows\system or c:\winnnt\system32, whichever is appropriate for your system.  You can then get it registered using the same process as above and HTML Help should work fine once again.
