I have 5 machines all running XP. When I tried to install Zimbra Desktop on three of them I get the same error. I have disabled Norton on them but that didn't help. Reinstalled multiple times. I have added the Zimbra folder in the Program Files to have permissions to everyone and the user. I have reinstalled 2005, 2008, 2010 C++ Runtimes.
Error is "ActiveX Component Can't Create Object"
