R – WIX MSI Package Uninstallation

windows-installerwix

I am using WIX for an installer package. When I uninstall the package by double clicking the original msi package everything is fine.

When I uninstall from the control panel it gives me a miminal UI uninstallation. I have written into my MSI a custom action which asks the user whether they want to uninstall some databases etc. This does not occur on the minimal UI uninstallation.

How can I make the uinstall from control panel work with a full UI?

A reply by Bob Arnson in this thread:

Yes, that's the behavior of the Add/Remove Programs applet. It always uninstalls MSI packages in basic mode after prompting. The only thing you can do is set ARPNOREMOVE to force a user to use maintenance mode -- and surface a Remove option in your maintenance UI.

EDIT: Perhaps look at the answer currently immediately below.

This topic has been a headache for long time. I finally figured it out. There are some solutions online, but none of them really works. And of course there is no documentation. So in the chart below there are several properties that are suggested to use and the values they have for various installation scenarios:

So in my case I wanted a CA that will run only on uninstalls - not upgrades, not repairs or modifies. According to the table above I had to use

<Custom Action='CA_ID' Before='other_CA_ID'>
        (NOT UPGRADINGPRODUCTCODE) AND (REMOVE="ALL")</Custom>

And it worked!

Php – Ubuntu PHP and sqlsrv_connect()

Linux based PHP does not support the sqlsrv_* functions. Those are only provided by the Windows driver. FreeTDS will provide you with access to the old mssql_* functions.
