HELP! Adding MSXML4 sp2 broke my installer

[toeknee]

The developers in my group went through and updated all their code to
use msxml 4 from the older 3 parser.

Now I've removed the MSXML3 parser and added the latest msxml 4 sp2
parser from msdn.microsoft.com

Now anytime I install I receive the following error message:

Error 1935. An error occured during the installation of assembly
"Microsoft.MSXML2.publicKeyToken="6bd6b9abf345378f",version="4.20.9818.0",type="win32",processorArchitecture="x86".
Please refer to Help and Support for more information.
HRESULT: 0x80070003.

The install is running on xp sp2, running windows installer service
version 3.01, this error occurs w/ and without antivirus and
antispyware running.

ANY HELP PLEASE????

Update / Solution

During my installation I install a system driver in a custom action. I
was able to figure out that if I removed the driver, the XML4 parser
install errors went away. I ended up moving the custom action that
installs the driver to the end in the "commit" phase of the
installation. This cleared up my errors. I also spoke with Microsoft
and they indicated this is a know issue and they have a workaround that
involves changing some folder names in the XML merge module.

Hello,

as I have the same problem right now and cannot find any information about
these directories, could you please tell me, which directories have to be
changed to what?

Thanks in advance

Did you ever find out what the solution to this problem might be?

I am currently experiencing exactly the same issue when trying to call a
custom action from a merge module - while installing on Windows XP sp2 with
MSXML3 previously installed.

Any help would be greatly appreciated!
