Error 2: There is already an existing User Authorization in the PC Access executable directory. You cannot install another User Authorization over an existing User Authorization.
You are attempting to install a user authorization into a directory that already contains a user authorization file. If the user authorization already on the hard drive is currently working, then there is no need to install another one now. If the user authorization on the hard drive is not currently working, then you need to manually remove the damaged user authorization before you can install a new one. Since removing a damaged user authorization is potentially dangerous to the rest of the files in your PC Access directory, follow the instructions for an Internal Error.
