How to write custom action to delete an installed file before install finalize

I want to write a custom action that will delete an installed file before installation is finalized, i.e after I install file "test" from msi.

I am executing it. Now I want to delete this file after it is executed. I have written a custom action for execution of "test" file. How should I write a custom action for deleting it?

This is not recommended because Windows Installer may detect the missing file and try to repair it. Instead, you can try this approach:

  • store the file in Binary table
  • use a custom action to extract it in a temporary location when installation starts
  • use another custom action to remove it at installation end

To extract the file you can use the Windows Installer API. You also need a DLL or VBScript custom action which receives the installation handle. Perhaps this tutorial will help: http://www.codeproject.com/KB/install/msicustomaction.aspx
