Problem with Googlebox updates

I'm running Windows XP Home SP2, Mozilla 1.7, Multizilla 1.6.4.0b and 
GoogleBox 14b. When I click on the Update icon I get a Dialog Box asking 
if I want to update to GoogleBox 1.4c. When I click OK, I get the 
XPInstallation Return Codes page with "USER_CANCELED, -210, User clicked 
Cancel on Install dialog" but honest, I didn't.

Are there some settings I need to change?

Oh, I also have the XP firewall activated and McAfee anti virus running 
but don't have problems installing other things like themes or even the 
original installation of GoogleBox. Also, I'm logged onto Windows with 
full Administrator privileges.

Regards,

Lou Petro
