Canon's Zoom browser is a wonderful product, keep it, considering it came with the camera anyway and I find it quite handy when the transfers occur and it is triggered without any effort.
Firewall and Avast have nothing to do with the problem.
It likely has to do with the broken or incorrect Visual C++ 8.0 CRT runtime library file msvcr80.dll
Perhaps yours is out of date or needs fixing, or perhaps this ZB can't use that library but some older one.
This might to the jobhttp://www.microsoft.com/downloads/details...;displaylang=en
or the 2008 version - at the bottom of the MS page.
On XP for Canon A590 I have ZB 22.214.171.124 and msvcr71.dll runs, you may need to find that 80 version which is likely in the link.
Did Canon help mention anything about the C++ version? What installs from the CD, what version of the C++ library?
