I have a VS08 solution with some Web/C# projects. I created an installer for it (web setup project) but when I run it in the target machine, I get the error "Installation Incomplete - The installer was interrupted before <MyAppName> could be installed. You need to restart the installer to try again".

I get this error even if the machine was just built and that is the first time I'm running it. I've searched the web for many solutions such as changing registry values related to MSI stuff but nothing has worked so far.

Any help is appreciated.

The issue was solved by removing IIS role from the server and then adding it again, with all IIS sub-roles enabled (not of them are really necessary, though).

It'soften a crash in custom action code. If you do the install and generate a log there should be more info:

msiexec /i <path to msi file> /l*vx <path to some log file>

Hi Phil,

The log tells me that SetTARGETSITE failed:

I have searched the web and found that this is due to IIS not being installed. However, IIS is indeed installed in my machine (the role is enabled, the service is there, up and running, and IIS shows up when I access http://localhost). Other suggestions was to re-register IIS using the aspnet_regiis tool.I did it but it didn't work as well.

PS: I'm doing such tests on Windows Server 2008, x64 machine.

Any suggestions?

I've seen this reported in this forum before, so search could turn up something. That error is "class not registered". You have an x64 system, so did set the setup project'sTargetPlatform to x64? Select the seup project in solution explorer then F4 (or View->Properties Window.

Aspnet_regiis - I'm thinking there's a 64-bit version of this in the 64-bit framework folder somewhere?

Yes, the target platform is x64 in the setup project properties window. I'm also using the 64-bit version of aspnet_regiis. But still getting the error...

For what it's worth, I found that I get this problem if there are no web sites configured on the target machine.

The VS Setup project does not seem able to create a new website, it only seems able to install to an existing web site, so one must exist before you run the installer.

If you try and run it before there is a website it will give the rather unhelpful "Installation Incomplete - The installer was interrupted before <MyAppName> could be installed." error. Using the log file method above you'll see the TARGETSITE is not set.

So create a new blank website using the IIS Manager and then re-run the installer and it should then work as expected.
