get product code from upgrade code via search

[bchernecki]

I am in need of a search that gets the particular product code of the previously installed MSI using the upgrade code.

I know this works with the Upgrades feature, but I can't use it for this case because the old .MSIs were not built correctly and don't play well when they run in upgrade mode. In a nutshell they only work for install and uninstall modes.


As such I've opted to manually uninstall the previous .MSI's with the 'Launch EXE With Working Directory' Custom Action. This works great as they simply translate to misexec /x {ca29811c-01c0-44a5-9228-6e6a57e6683e} /qn

However it would be more valuable to able to find the product code dynamically so I only have to have ONE custom action rather than X for each product
misexec /x [product_code_property] /qn

Here are my searches

Is this possible?

P.S. These aren't the ACTUAL product codes for my installer

Hi and welcome to our forums.

I apologize for the delayed reply.

Please keep in mind that in order to automatically uninstall all the versions of a product based on its Upgrade Code, you can simply go in the "Upgrades" page, use the "New Upgrade" toolbar button and add that Upgrade Code there.

If you want to enumerate the products with a specified Upgrade Code you can use the "MsiEnumRelatedProducts" function.

Hello Eusebiu

Thank you for your reply. I am aware of and have utilized the upgrades feature you described. However it does not work for old buggy .MSI that only uninstall during the uninstall mode, not during upgrade mode. Thanks MSIWrapper...

In a nutshell this MSIWrapper tool created a custom action that has a condition REMOVE ~= "ALL" AND NOT UPGRADINGPRODUCTCODE.

So hence why I am manually uninstalling with msiexec.

The MsiEnumRelatedProducts sounds interesting. Could you please expand on how one might utilize this within AI?

Hi,

In order to use the "MsiEnumRelatedProducts" function you need cu create a DLL custom action where you call it as described in its documentation. You can create a custom action written in C++ or you can use it as discussed in the thread below:
