The 429 error is an annoying issue that happens when Amazing Charts tries to instantiate an object. In human terms, that means that when Amazing Charts goes to create something like a patient record (in the memory of the computer), it can't.

The reason usually has to do with a missing or unregistered dll. In human terms, that means that some of the code used by Amazing Charts and other programs, can't be found or loaded up when it is needed.

Most times, this is because during the installation process, the dll wasn't able to register itself (in human terms, that means that the dll couldn't tell the operating system where it is located).

User Access Control (UAC) in Vista, sometimes blocks the dll from registering, but doesn't tell the user it has done so - so everything seems to install fine, but then one gets that frustrating 429 error (can't create object).

The fix is to either manually register the dll (using regsvr32 at the command prompt - which I would not recommend anybody to try unless they know what they are doing), or as Dr. J did, turn off UAC and reinstall. Although this issue is relatively rare, our tech support folks do regularly see it, and must manually register the dll for some clients.

Keep in mind before simply turning off UAC (the instructions for which can be found by googling 'turn off uac") that the concpet of UAC is helpful at preventing your computer from being taken over by malware and viruses. Unfortunately the kinks of it have yet to be worked out by Microsoft.
