Detect Previous Version

I want to detect the current installed version of my product. The command Detect Previous Version only returns the path of the product. I'm interested in [PRODUCTVER] defined in my previous installation. Is this possible to find anywhere?

What you can do is to read this information from the Registry. It's stored under \Uninstall\{YourGUID} - read the DisplayVersion value.

Does this help?

You check this version in the WebUpdate program, and I went to see its source (quite cool, btw, that this is written IN SetupBuilder :). There I see you fetch the current version from HKLM\Software\Lindersoft\WebUpdate\Apps\GUID.

Which method do you recommend, the UNINSTALL or the WebUpdate way?

:)

I would suggest to use the UNINSTALL method. BTW, please check both HKLM and HKCU!

I can't seem to find these Uninstall sections in the registry. What is the exact path?

Found one under HKLM\Software\Microsoft\Windows\CurrentVersion\Uni nstall
, but not any under CU.

Now the next question, the main application inserts a uninstall here, and I see it has the correct version.

But after running wupdate and updating my version, this registry value still contain the old value.

If the Uninstall entry does not exist then you have installed all programs with Admin rights ;-)

BTW, it is your responsibility to update the version number. And to have full control, you can use your own registry key! You can add a version number, last update date, etc., etc. Use the Edit Registry and Get Registry Key Value functions.
