Hi Stefan Krüger
I want to Install MSXML3 MergeModule Conditionally.ie if msxml3.dll is in the target machine, setup shouldnot install the merge module.If not it should install it. I am not sure whether it is possible or not.I am Using ISWI 2.01. Pl reply.

Never tried this, but I think it should be possible this way:

1. Use the AppSearch table (together with Signature and DrLocator) to find the msxml3.dll
2. Add the merge module to a feature with a condition based on the search results from step 1.

Hi Stefen
i tried the way u told.but it doesnot give the result. ie here i am giving the

porcedure that i done.

Signature Table
================
SignatureFileName

MSXMLDLLmsxml3.dll

APPSearch Table
===============
PropertySignature

MYAPPMSXMLDLL

DRLocator Table
===============
SignatureParentPathDepth

MSXMLDLLC:\Winnt\System32 0

Then i add one feature namely MSXMLDLL
Install Level for this is 101.

Using the Condition Builder i made the followings
Condition is MYAPP=C:\Winnt\System32
Level     is 99

so when the setup run it will search for the dll .if found it should set the MYAPP Property

to C:\Winnt\System32. so the condition becomes TRUE.so the MSXML.msm should be installed.
because the install level is less than 100.
But here the MM is not installed.i think the Property is not set to C:\Winnt\System32.
Pl tell me where i am making mistake.

I think that MYAPP would be set to C:\Winnt\System32\msxml3.dll. A log file or the debugger will tell you exactly. BTW you should not hard code the path.

You could also open the merge module and edit the install conditions. It is cleaner.
You could both use Orca and ISWI.

good luck

I've tried this to conditionally install MSDE but it seems to do not work.
MSDE merge module is always installed.
