PDFSam 4.0.4 Installation error message - confusing

[SelfMan]

[Window Title] Windows Installer [Main Instruction] This installation package is not supported by this processor type. Contact your product vendor.

I am on Windows 7 Pro x86 and this message will be confusing for all the x86 OS owners.

The error message should say something like: "This installation package is designed for a 64bit based operating system and is not supported by the 32bit." It has nothing to do with the CPU itself.
