Skip finish page after updating is complete

Hello. I'm trying to make the update process as seamless as possible, trying to avoid the user having to do anything. At program launch, I create a process to use wyUpdate.exe via the command line to check for existing updates (with parameters "/quickcheck /justcheck /noerr") and if found, I launch wyUpdate with the parameter "/skipinfo".

In the wyBuild tool, I check the "Execute file after updating is complete box" for the main executable because I want the program to launch itself again post-update. It does this correctly, however, there's then this wyUpdate window hovering in the back on the finish page, waiting for the user to close it.

Is there any way to automatically close this finish page so wyUpdate will finish updating, launch my application and close itself, having required no user input to do so? Thanks!
