Trying to start FB7 trial on my laptop:

---------------------------  
Error  
---------------------------  
Unable to start FinalBuilder:  
Failed to initialise MSXML 3 : Interfaccia non registrata, ClassID: {88D96A05-F192-11D4-A65F-0040963251E5}  
---------------------------  
OK&nbsp;&nbsp;   
---------------------------

I've installed DotNet 2.0 and MSXML3

(Windows XP&nbsp;Pro 32 bit)

What can be the source of this error?

Hi Fabio,   
  
We changed the minimum version of MSXML to version 6 in FinalBuilder 7 though unfortunately it looks like we haven't updated the error message correctly, could you please download MSXML 6 and let us know whether you still get the error?   
  
Regards,   
Paul.
