Auto Updating - Launcher Patch

Hey Ragezone,

I have my old launcher which doesnt Auto Update Encrypted MRS Files, So i made a New one which does and now i want the old one to update and patch to the new one, so i added the new one to the Apache/www/gunzweb/GunzUpdate/ and now when i run the old launcher it gives me this error:

ERROR : File copy error : .\National Launcher.exe : The process cannot access the file because it is being used by another process.

My old Launcher name is National Launcher.exe
My new Launcher name is National Launcher.exe

They have to be the same name inorder to patch the old one, but i get that error, so please help me out.
