使用wix安装程序首次设置时，自定义事件未执行

Question

I am trying to develop an application using SingnalR which will install into client machine and continuously give me update on a particular port. I made client setup using WIX and added a custom event to register port to the client machine. Now the issue is, while I am going to run the setup for the first time on client's machine, my custom event is not getting fired. But if I run the installer for second time, it is getting fired. I don't know what is the issue.

.wxs file is as below,

It would be great if you can help me to get rid of this issue.

Answer 1

You have set the condition to run only if the product already installed.

Change the condition in the custom action to Not installed.

<Custom Action="addPort" Before="InstallExecute">NOT Installed</Custom>
