If you put the libxml2.dll in C:\WINNT\system32, and then run

   C:\> perl -MXML::LibXML::Common -e "print 1"
[download]

does that produce an error? If so, is it the same error as before?

I tried and got the following

U:\>cqperl -MXML::LibXML::Common -e "print 1"

I have been cheking your other forums and you had explained about copying this dll to C:\winnt\system32 folder. Doesnt work for me perhaps i am using a customized version of perl!
thanks

That is a strange result - it suggests that some of the configuration information in your Perl installation has some values probably set from the machine where it was built, and hence don't necessarily match your system. That may be contributing to the problem. What happens when you run:

  C:\> set PERL_DL_DEBUG=1
  C:\> perl -MXML::LibXML -e "print 1"
[download]

Also, what happens if you place libxml2.dll in the same subdirectory as Common.dll, which is used by XML::LibXML::Common?

tried and got this

the common.dll is present in C:/Program Files/Rational/Common/lib/perl5/site_perl/5.6.1/MSWin32-x86-multi-thread/auto/XML/LibXML/Common/ folder

Also i tried placing the libxml2.dll in the same folder as common, but still i get the same error!

Just for the record, below are the list of files i have

And libxml2.dll is placed in

C:\Program Files\Rational\Common\libxml2.dll
[download]

i hope this could throw some light!
