[WiX-users] Command Line Parameters to Deferred Custom Action on Vista

[Rajesh P]

Hi,

I am developing a WiX installer for Vista. I have a requirement to send some
command line parameters to a Deferred Cusom action.
My inital attempts to send the parameters using public property as follows
have failed:

I tried : msiexec /i myinstaller.msi CMDLINEPROPERTY=arg1 arg2 arg3

But till now i have not been able to get these arguments reach my custom
action where i am calling MSIGetProperty() go retrievet the property value.
I even tried reading the value from CustomActionData property , but no
success yet.

If anyone has successfully achieved this on a Vista platform , please help
me !!

Thanking you in Advance,

Rajesh

[WiX-users] How to prevent downgrading when doing Minor Upgrade

[Rajesh P]

Hi

Is there a way iw WiX to prevent downgrade with minor upgrades.
Can we write a custom action to verify and compare installed product
version. If yes, can someone suggest some Msi api's that can use in my VC++
custom action dll.
Is there any other easier way to achieve this.

Thanks,
Rajesh
