You are dealing with a computer challenged person here.  I have platinum installed and running well.  I have just purchased a new computer that is 64bit.  I would like to change to 64 bit platinum but I don't see any place to change the download to 64 bit.  Any help would be appreciated.

The Command Center detects the OS and installs the appropriate version. Running the installer manually provides a choice of 32 or 64bit early in the installation. Both versions are included in the installers.

Thanks for the reply,  I appreciate it very much.
