Q: On installing AVT FirePackage I get Microsoft error 1720 or error 1722. Please advise what this means and how to overcome.
A: The most common source of this problem is choosing "install driver" but not having a 1394 Firewire card installed. See screenshots/explanations for more info.
If the above tips do not clear your problem, we recommend using diagnostic logging mode as described below.
Please see Troubleshooting MSI Error 1720 and command-line options of Windows Installer for logging.e.g.: msiexec /i AVTFirePackage.msi /lv* msi.log
Please examine the log files for error codes if you are comfortable and get an "aha" insight, or send them to us for further analysis, at firstname.lastname@example.org. Also tell us what brand and model of PC you are using, with what OS and Service Pack, and with what brand and model of 1394 adapter card.
