Launch updates check from application start

[Dredgewood]

I must be having a case of "Can't see the forest for the trees" because I cannot find an example of how to launch the updates.exe from an application start event. I am not looking to start it from a shortcut, but from the event itself (if possible). The situation being I am writing an installer for a windows Addin, and I want to check for addin updates on the launch of the windows application.

So far I have in "Updater" set the execution to Automatic and configured the task:
Command Line: -silentall -nocheckfreq
Schedule: On an Event

Query (which I know is incomplete but i can't find a working example to see where I@m going wrong):

<QueryList>
<Query Id="0" Path="Application">
<Select Path="Application">*[EventData[Data and (Data='WHAT YOU SEE IN THE GENERAL TAB')]]</Select>
</Query>
</QueryList>


Can anyone point me in the right direction or provide/link to an example of what I'm trying to do?

Cheers

Hello and welcome to our forums,

To achieve what you need, you should make sure that you escape both square bracket characters ([,]) inside the query content you add in Advanced Installer as it follows:

Code: Select all

<QueryList>
<Query Id="0" Path="Application">
<Select Path="Application">*[\[]EventData[\[]Data and (Data='WHAT YOU SEE IN THE GENERAL TAB')[\]][\]]</Select>
</Query>
</QueryList>

This is happening because the query field is of formatted type, which means that any string with the following format: [string] will be treated according to our "Windows Installer Formatted Type" article.

Hope this helps!

Kind regards,
Catalin
