Error when installing version 3.00 build 3

[TheGame]

Hello Support,

I recieve this error message when I am trying to install version 3.00 build 3:

Error opening file for writing:

C:\Program Files\Poker Tracker 3\Pokertracker. exe

Click Abort to stop the installation,
Retry to try again, or
Ignore to skip this file.

What can be the problem. I am a "upgrading user", but I have tried to install without and with PostgreSQL.

Thanks in advance.

You need to make sure PT3 isn't running.
Please see: Download and install PT3.
