如何使用 WiX 安装程序注册文件类型/扩展名? [英] How to register file types/extensions with a WiX installer?

问题描述

I didn't find an explicit answer to this question in the WiX Documentation (or Google, for that matter). Of course I could just write the appropriate registry keys in HKCR, but it makes me feel dirty and I'd expect this to be a standard task which should have a nice default solution.

For bonus points, I'd like to know how to make it "safe", i.e. don't overwrite existing registrations for the file type and remove the registration on uninstall only if it has been registered during installation and is unchanged.

解决方案

Unfortunately there's no way to do a "safe" association with Windows Installer.

We just write everything out to the registry and then have a separate component that takes over the system-wide default and is only installed if no other application has already registered itself as the default.

With Vista there's the new "default programs" interface, again you write everything out to the registry. Here's a complete example that we're using in our installer. (WiX 3.0)

Update: 12 months have passed since my original answer and I have a better understanding of file associations. Rather than writing everything manually I'm now using proper ProgId definitions which improves handling for advertised packages. See the updated code posted in response to this question.
