Hi together,

I don't know whether this is the right thread for my problem but perhaps
anyone can help me.

I just installed the electronic exam preparation software (Microsoft Press
Readiness Review Suite) from the original Microsoft Training CD that
comes with the book "Managing and Maintaining a Microsoft Windows
Server(TM) 2003 Environment" (70-290).During installation the this first
error comes up:

"The Windows Installer service cannot update the system file
C:\WINDOWS\system32\msxml3r.dll because the file is protected
by Windows."

The installation continues after confirming the error message with OK.
Unfortunately there are further errors when I try to start the
application.While starting the application the error in this next error
is shown:

Window title: "Application Error"
Window text:
"Error Number: 1000
Error Source: frmMain.MDIForm_Load
MDIForm:Load
[MsLocalWare] [429] ActiveX component can't create object"

When I choose "StartNew Test" from the "Test" menu the third error
appears:

Window title: "Microsoft Press Readiness Review Suite"
Window Text:
"Run-time error '91':
Object variable or With block variable not set"

Closing this error causes the whole application to quit.

I searched for information about the error in the internet but couldn't
find any suitable hints. The Microsoft Knowledgebase contains
articles concerning ActiveX errors but not exactly with this application.

I tried to use the software with "Windows XP SP3" as well as with
"Vista Ultimate SP1" - in both cases the sameerrors appear. Both
operating systems are the German version.

I think the basic error is the first one concerning the file msxml3r.dll.

I've already tried to install several versions of Microsofts MSXML Parser
and even updated the msxml3r.dll seperately by turning off system file
protection.

What shall I do to solve the problem?

Thank you for your efforts!


Best regards,
Michael
