Hello Mateusz,

I am not quite sure I fully understand your scenario here.

However, if what you want to achieve here is to detect whether the uninstlal is done from Control Panel, here is how you can proceed:

- go to "Product Details" page

- check the "Override Windows Instlaler programs list entry" option

- go to "Table Editor" page

- "Registry" table

- modify the "UninstallString" so that you set a property when the Uninstall String is used, e.g.:

Code: Select all

[AI_UNINSTALLER] /x [ProductCode] AI_UNINSTALLER_CTP=1 UNINSTALL_CP="true"

You can then use "UNINSTLAL_CP" property to detect whether the uninstall was done from Control Panel.

Hope this helps!

Best regards,

Thank you for your reply.

I don't know why, but when I tried your sollution, installer didn't set property UNINSTALL_CP when I'm uninstalling my program from windows "settings -> apps and functions". It's blank.

However, in my scenario I tried checking value of AI_UNINSTALLER_CTP to show/hide controls when a program is installing/uninstalling and it works.

So I think my problem is solved. Thanks.
