Newest version, includes updated keygen, version 1.7 (which adds support for Vegas Movie Studio HD 9.0).
Tested and confirmed working, virus-free (If antivirus reports virus, trojan, or whatever it’s false positive)
Instructions:
Extract after downloading, read the README file
IMPORTANT NOTE: For Vista/ Windows 7 users, run the keygen and the installation as an Administrator user.
Even if you’re on an Administrator account, you must run the program and keygen as an Administrator. How? By right clicking on the said program, click “Run as..” or “Run as administrator” in Windows 7, select an Administrator account, type the password if required, click “Ok”

Please download the version that is meant for your OS, meaning Windows 64 bit should use Vegas 64 bit, same with 32 bit. There is a problem currently with the keygen not being able to register Vegas 32 bit onto a Windows 64 bit environment.

FOR EVERYONE – You must copy the activation code correctly, it is not just what you see, highlight the code to the end. There are 6 groups of 9 characters, if the activation code still fails, delete the registry keys again, re-run the program and keygen. Generate a different key and try again.

Try patching the program again if it still doesn’t accept the key and re-enter the serial and activation code. The serial and activation code are in pairs, meaning you can’t click generate again and use a different activation code for the previous serial.

Some common mistakes that people make are:
1. Not running the keygen and Sony installation file as an Administrator account
2. The keygen is set on default, meaning the Sony Vegas option isn’t selected from the drop-down box in the keygen.
3. The keygen isn’t placed in the Sony folder or isn’t directed to the right directory to patch.
