How the update process knows current client version

[prasanth.nair]

Hi,

I am creating a new update pack for my installer as in the help file. I am curious to know how the update process finds the current version of app installed on client machine.


Thanks

Dear Prasanth,

The update process reads the current version from the following registry path: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{ProductCode}\Version.

Is this in MSI Code ?

[giaviv]

No, its a part of the InstallAware engine that is not exposed in the MSIcode.

I am trying to create a shortcut using the below code.

Create Shortcut $STARTUPDIR$\ to $TARGETDIOR$\_ClientEgents\Atlas.WindowsAgent.exe

Here is error message :

Error during build: Unable to compile MSI action create/advertised shortcut.

Any idea about this ?

Perhaps it was a copy and paste error but did you mean TARGETDIR and not TARGETDIOR?

I need to add the app in start up for all users and it has to check for updates when ever I start the app. I dont want to use the scheduled tasks for updates.changed the project properties to Manual update checking and following the same steps provided with http://www.installaware.com/blog/?p=12
I can not see the short cut in all users folder and also in my start up folder.

Dear prasanth.nair,

Please follow up on your other thread - thanks.

Dear Prasanth,

I have been advised that I was mistaken - the values you were asking about before are hard-coded into the installation binary, and is not read from the registry.
