Problem with MSXML - Interface not registered...

[Arif Ali Saiyed]

Hi All,
I was using MSXML 6 to read an XML file ...which is on the
web..and things were working fine for me ....
after I uninstalled IE 8 and moved to IE6 .... It has stopped working
and I am getting and error

"Interface not registered"....


1) however the same program (same binary ) works fine on two more
friends of mine....

2) I Changed my default browser to Firefox that also did not help

3) I then also tried chanding path of XML.... i made it c
\xyz.xml ... and then it works ...
only when I make it http://processpriority.svn.sourceforge.net/viewvc/processpriority/pad_file.xml
it doesn't work ....

Any idea what's wrong ...below is the code snippet which was working
fine earlier and now it;s not working
However I am not too sure that IE degradation has caused this ... I am
just suspecting..
