I’m getting the message “library not registered” when attempting to open a navigator in quickbooks with errors on the various qpg files that it tries to open. On speaking to their tech support who had me remove the software, install it, install in safe mode, remove, reinstall in normal mode, then download the updates again (thankfully I had saved the 80mb patch file to disk so I didn’t have to download it again) he then recommended that I repair Internet Explorer as this was the problem. Unfortunately you can’t repair IE in xpsp2 (see KB318378 so I reinstalled xpsp2 again.
At this point, he admitted, several times, that NOONE in support can tell me what ocx’s or dll’s are required by the various pages used in the Navigator pages. I asked who could tell me which files are needed, but he kept telling me to repair internet explorer instead.
I’ve heard Intuit’s support is notoriously bad and I now believe it. I would have expected him to check my internet explorer security settings, popupblocker settings and it was only after about 40 minutes on the phone that he checked what version of quickbooks I was using (pressing F2 gives that information)
He was not interested in the fact that there was an incompatibility issue with Quickbooks Premier 2002 and Windows NT and that I am getting the same type of message. Unfortunately in this case, the pc that has a working copy of quickbooks and the faulty pc have the same version of comcat.dll
From the sounds of it, there is a permission problem in the registry under HKEY_CLASSES_ROOT\TypeLib\ but whereabouts I am not sure. It’s time to use regmon from sysinternals again to monitor for access denied messages when launching quickbook navigators.
