Some installations of the HTML Help Compiler will report the error code HHC6003 referencing file itircl.dll. In fact, QuickTest® Professional has a documented issue where this error is often received after installing QuickTest® Professional. This is typically caused by the itcc.dll file being missing or improperly registered. Check if the following file exists on your system:

C:\Windows\System32\itcc.dll

If it does not exist, use the links above to download and re-install the HTML Help Workshop. If it does exist, it probably just needs to be re-registered on your system. You can re-register the file by executing the following command from a Command prompt or the Run window.

regsvr32 C:\Windows\System32\itcc.dll

Note:   The exact path to the itcc.dll file may vary based on your system configuration.
