Changing [INSTALLDIR]

[CChong]

I have an application package that depends on an ini file that is parsed with install script code.
In this ini file the INSTALLDIR is defined.

However I try I don't seem to be able to get the installation to recognise that I have changed this property using a line of the form:

MsiSetProperty ( hMSI , "INSTALLDIR" , "D:\\" ) ;

And I can show that the property has changed succesfully.
I have tried setting the action to run straight away, and at several levels in the order of install with little success.

My installation works fine for all other parts if I define the property in the command line:

msiexec /i ITO.msi INSTALLDIR=D:\

Is there some way of forcing the property early enough in install script?

Depending on where your InstallScript code is being called, you might try using MsiSetTargetPath instead of MsiSetProperty; in what function does your code appear? When is it being called?

I now have this working alright as I want for a hardwired directory. Say D:\\
Both for silent and non - silent install. (this was what was holding me back originally in the ordering of the actions)

Now my problem is reading from the .ini file.

At the moment I am using the SOURCEDIR property to find out where the .ini file is located (ie the same directory that the installation MSI is running from - by design)

My problem lies in that this property is not defined until CostInitialize, but for the the installation directory (initial issue ) to change, then the action needs to be BEFORE the CostInitialize action.

A catch 22 situation? I need another method to know where to open my .ini file, before CostInitialize.

Any thoughts?

Scratch that, I have found the CURRENTDIRECTORY property (found it from a verbose log)

Phew!
