windows installer - How to uninstall MSI using its Product Code in c#

Question

I know We can uninstall a windows application using its MSI by passing command arguments as follows,

Process p = new Process(); 
p.StartInfo.FileName = "msiexec.exe"; 
p.StartInfo.Arguments = "/x "C:\MyApplication.msi"/qn"; 
p.Start(); 

But what i want to know is how can we uninstall the application without using MSI ? In the above scenario I should have the MSI in the specific location to uninstall this application, If i could unstaill using product code then I dont need to have the MSI in the target machine.

According to MSDN, You can uninstall it using the product code:

msiexec.exe /x {your-product-code-guid}

When you use the product code, it uses the cached MSI from C:WINDOWSInstaller.
