C #. Net uninstall the application

Method 1:

In the packaging project, locate the "msiexec.exe" file (generally found in c: windowssystem32 (in the system directory ).

In the file system view, select the application file, right-click msiexec.exe and choose "create shortcut", and rename the shortcut to "uninst ".

Change the shortcut Argmuments to "/x {product ID}", and the value of the product ID is the ProductCode attribute value of the package project.

Method 2:

Enter the installation package, and write down the ProudctCode (select the solution Resource Management root directory such as Setup1, and then view the property tag, not the right-click attribute ).

Use Vs. Net to create a new console program uninst.exe file.

The Code is as follows:

Using System;
Namespace uninst
{
/// <Summary>
/// Summary of Class1.
/// </Summary>
Class UnInstall
{
/// <Summary>
/// Main entry point of the application.
/// </Summary>
[STAThread]
Static void Main (string [] args)
{
String sysroot = System. Environment. SystemDirectory;
System. Diagnostics. Process. Start (sysroot + "\ msiexec.exe", "/x {850FED90-20D0-4EBA-BEDB-3D9DBA25F6EC}/qr ");
}
}
}

After compilation, add the generated uninst.exe file to the installation package and regenerate the installation project.
