MSI Custom action running with admin priviledge

[dannyw]

I am working on a basic MSI project. I have a custom action which downloads some information from a server and writes it to my install folder.

At first i set the custom action to be "Immediately execution", but it failed to complete. Then I found out that the custom action needs to run with admin priviledge to create file under the folder in Program Files folder.

I did a search and found a solution to set the CA as "Deferred Execution in System Context". However my CA cant access the MSI properties with this setting...!

So I wanna ask if there is a setting for CA to run with admin right, and yet to be able to access MSI properties.

Or did i miss something here? Thanks.

i found the solution for my problem which is to use the CustomActionData property.

you are true that setting a custom action in "Deferred Execution in System Context" will be executed with privileges.
But in deferred execution you can't access the MSI properties directly.
Check this for deferred custom actions.
