Can my installer detect a prior installation?

[NewsArchive]

Hi,

Is it possible to add something to my SB installer to check for prior installations of my software and then install the new version to the same drive and folder?

Hi Abe,

Sure.

Just store the path to the install in HKLM (which is accessible to you in
the elevated installer) and use that as the default for the install path.

Or you can go the route of conditionally hiding the dialog to select a path
if a previous install is found.

I prefer to just set the default and leave the dialog available though.

You will probably be using a unique GUID so look for
HKEY LOCAL MACHINE\Software\Microsoft\Windows\CurrentVersion\ Uninstall\{MyAppsGuid}
Then look up InstallLocation for the path its installed to.

SB does a good job sticking to the MS unlike other installers I see installed under the above registry key.

You can use the "Detect Previous Version..." script function :)
