Re: [WiX-users] Question: Migrating Existing Installer to WindowsInstaller

[Derek Cicerone]

First off, welcome! There’s some information that can help guide our answers for you: When does your product ship? What is your product (just curious)?  More specifically, what does it interact with (COM, services, MSMQ, IIS, SQL, etc…)? How does the C# installer install things?  Does it use the Installer classes or manually set registry keys and copy files?   To answer some of your questions: I’m not sure how the upgrade story would work – it all depends on how you currently handle uninstall and upgrade scenarios.  Is there something you’d need to run to perform an uninstall on the previous version (would it be managed code)?  Once you get all customers on an MSI deployed setup it should be easy to have them all use the same technology after that point.   Thanks, Derek From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rick Glos Sent: Thursday, July 27, 2006 12:09 PM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Question: Migrating Existing Installer to WindowsInstaller   Hello, I’ve spent the last two days getting familiar with WiX, the windows installer, and going through the great tutorial on WiX (http://www.tramontana.co.hu/wix/).  I especially liked the article posted a year ago (http://msdn.microsoft.com/smartclient/default.aspx?pull=/library/en-us/dnwingen/html/wixsetup.asp) that talks about doing the installer during the development cycle and not at the end of it.  We are badly in need of doing this. I have a question however.  How do we migrate from our current installer to the Windows Installer for existing customers? We just released version 5.0 of our product.  Spending 6 weeks updating our installer (we have a custom C# installer).  I can see our new customers instead using a new .msi for later versions (5.5, 6.0, etc).  What do I do about our existing customers when they wish to upgrade?  They’ve never installed originally with a Windows Installer.  How do I get them on the same track?   Thanks for any advice, Rick Glos
