Hi misters,

How I can do this in C# ??

Dim installer As Object

installer = CreateObject("WindowsInstaller.Installer")

Dim products As Object = installer.Products



For Each strProductCode As String In products

'Console.WriteLine(strProductCode)

Dim strProductName As String =
installer.ProductInfo(strProductCode, "InstalledProductName")

If strProductName = "Something" Then

'That's it.

End If

Next


Thanks !!!

Hi, i think this following code works, try it :

Type type = Type.GetType("Windows.Installer");

WindowsInstaller.Installer installer = Activator.CreateInstance(type);

foreach (string strProductCode in installer.Products)
{
Console.WriteLine(strProductCode);
string strProductName = installer.ProductInfo(strProductCode,
"InstalledProductName");
if (strProductCode == "Something")
{
}
}

Type type = Type.GetType("Windows.Installer");

WindowsInstaller.Installer installer = Activator.CreateInstance(type);

thanks mister !!!

I need add some reference about Windows.Installer in my csproj ??? which
Reference, where the type WindowsInstaller.Installer contains within the
reference ?

How can I detect that Windows Installer is installed in my machine ??

Thanks again, mister.

By using CreateInstance or CreateObject, you don't need to add a reference.
You should check for an exception when calling this to see if the class is
not registered, but I believe there will be a windows installer on every
machine.

You must add a reference to "C:\Windows\System32\msi.dll"

Here is the C# code reviewed :

Type type = Type.GetType("Windows.Installer");

WindowsInstaller.Installer installer = (WindowsInstaller.Installer)
Activator.CreateInstance(type);

foreach (string strProductCode in installer.Products)
{
Console.WriteLine(strProductCode);
string strProductName = installer.get_ProductInfo(strProductCode,
"InstalledProductName");
if (strProductName == "Something")
{
}
}

You are right, when casting to the WindowsInstaller.Installer type you need a
reference. If you are adding a reference though, why not just use:

WindowsInstaller.Installer installer = new WindowsInstaller.Installer();

Exact, i just respected that he wrote in VB.
