I tried that one already. It always returned 0 no matter what version my bundle had.

Betreff: Re: [WiX-users] Custom Bootstrapper Application: Problem whentrying todetect if Bundle is already installed Could you use the built-in variable WixBundleInstalled instead ? I'm not sure if that's version specific or not. It might be worth a look. -----Original Message----- From: Frauenhoffer, Sabine [mailto:sabine.frauenhof...@haufe-lexware.com] Sent: 27 September 2012 14:13 To: wix-users@lists.sourceforge.net Subject: [WiX-users] Custom Bootstrapper Application: Problem when trying todetect if Bundle is already installed Hi there, I have a problem when trying to detect whether my Bundle is already installed. My usecase is as follows: I am creating a bundle with a custom UI. On startup I need to check whether my bundle is already installed in the exactly same version to determine if I have to show the maintenance page (if the versions match), to block installation(if a newer version is already installed) or show the install page (else). So I make a call to _bootstrapperApplication.Engine.Detect(); My first idea now was to handle the event _bootstrapperApplication.DetectRelatedBundle and somehow determine whether the productcodes are different. This is not possible as I can't get the product code of the bundle that is going to be installed. Then I thought it might be an idea, to check for some package which is unique for my product. So I added the line _bootstrapperApplication.DetectPackageComplete = DetectedPackage; (see below) but it doesn't work as I expected: private void DetectedPackage(object sender, DetectPackageCompleteEventArgs e) { PackageState.Obsolete if (e.PackageId.Equals("mypackage", StringComparison.Ordinal)) { _state = (e.State == PackageState.Present) ? InstallationState.DetectedPresent : InstallationState.DetectedAbsent; } } - If for example version 2.8 is installed and the Package in my Bundle now has version 2.7 it returns PackageState.Absent (or Obsolete? I can't reproduce it at the moment) which is just fine - If version 2.8 is installed and the Package in my Bundle now has version 2.8, too, it syas e.State = PackageState.Present which is correct, too. - But if version 2.8 is installed and the Package in my Bundle now has version 2.9, I get e.State = PackageState.Present and would show the maintenance page although I would need to show install page and install the newer version. Is this intended or is it a bug? Am I getting something wrong? What I am doing as a workaround is, on DetectRelatedBundle event I make some very ugly version comparison. Is there any other option? Any help appreciated, thanks in advance! Regards, Sabine ----------------------------------------------------------------------------- - Everyone hates slow websites. So do we.
