Depends on what version number you mean. If you have a preexisting product installed with the same ProductCode (Product/@Id) and ProductVersion (Product/@Version) as the new product then you will run into problems if you don't author the package correctly. I would start out by reading the following: Patching and Upgrades - http://msdn.microsoft.com/en-us/library/aa370579.aspx Small Updates - http://msdn.microsoft.com/en-us/library/aa371855.aspx Minor Upgrades - http://msdn.microsoft.com/en-us/library/aa370037.aspx Major Upgrades - http://msdn.microsoft.com/en-us/library/aa369786.aspx How To: Implement a Major Upgrade In Your Installer - http://wix.sourceforge.net/manual-wix3/major_upgrade.htm Upgrading with Windows Installer is tricky because it has a lot of moving pieces but I don't think it is necessarily hard as long as you follow some reasonable best practices. The "How To: Implement a Major Upgrade In Your Installer" makes it easy to author major upgrades which is probably what you want to do since you haven't thought about this problem from a Windows Installer perspective yet. There are other resources online you can search for.
