Automated Windows Installer Properties from .INI (Embedded VBScript)

Download: [download#2#size#nohits]

Have you ever needed the functionality to read the property values from an .ini file, every time a installation or repair is run?

This small script created for Windows installer, will do the job.


Automatically reads a ini file located in the MSI SOURCEDIR property.
Each parameter in the ini file is read into the property that
have the same name.
ex. “DaysSerial”=”0100000” line is read in to property named
DaysSerial and setting the value to 0100000
System works both with “DaysSerial”=”0100000” ini format, or DaysSerial=0100000 ini format.

If you later change the ini file at the source, and do a repair of the msi on the client, the new settings will be used.

NB! I also tried to make a script that could use custom named ini file, based on the commandline parameters, but it is, as far as i know, not possible. If you have an idea of how to do it, please do not hesistate to comments this article.

The problem is that if you later do a repair on the package, it will use the default settings, instead of the custom named ini file. This is why i “hardcoded” the ini filename into the package.


Put into MSI package execute deferred after “InstallInitialize” and
“ResolveSource” actions. In this example i have used VBScript Embedded.
NB! You might have to insert the “ResolveSource” action, since it is not allways default.




This script was tested in a msi package created by Visual Studio 2008
and edited in Wise Package Studio.
Coretech A/S is not responsible for any damages the script could cause.

    Great script! Exactly what I was looking for.
    The only problem is the download doesn’t work.
    A error 404 occures with the following text:

    Fatal error: Cannot use object of type WP_Error as array in D:xampphtdocsblogwp-contentthemescoretechsidebar.php on line 52

    Hello Elwin!

    Thank you.

    I am sorry that you could not download.
    We have recently updated our blog system.
    The error is fixed now, and the download should work.
    Thank you notifying us about the error.

    Have a nice day

    The download is working now.

    I’m quite new to VB2008 and I don’t understand how to make the script working.
    I have made a office addin and created a Deployment Project.
    The script is added to the Deployment Project.

    I don’t understand the Usage part of your description.
    Where do I find “InstallInitialize” and “ResolveSource”?

    Thanks in advance.

    Hello Elwin,

    I am sorry for the late reply.

    I dont think you can edit the script part of the MSI Package in visual studio!

    That is why i had to edit it in Wise Package Studio.
    You might be able to put the script into Custom Actions in Visual Studio, but i am not sure how.

    I always use Wise Package Studio for creating and editing packages, it has many more functions than Visual Studio.
    The only time i use VS for MSI packages, is when i am creating an installer for my own projects.
