Folder Lock Self Exe lockers in USB issue

Hello,
I currently have a registered license for Folder Lock v7.5.2. Prior to v7.5.0 I had created a portable locker on a USB as a xxx.exe. My virus scan, Bitdefender had identified the .exe as a virus and deleted the file. Bitdefender never quarantined the .exe file but I was able to retrieve the file from the USB using a data recovery software. Now, when I attempt to open the xxx.exe file, I receive a windows error of "The version of this file is not compatible with the version of Windows you're running. Check your computers system information to see.....".

I currently have Windows 7 64 bit and used the same Windows 7 64 bit when I originally created the portable locker on a USB.

Also, I originally created the portable locker using either version 7.2.5 or 7.2.6 or 7.3.0. If I uninstall v7.5.2 and reinstall an earlier version of Folder Lock that I just mentioned will this resolve my windows error and allow me to open my portable locker?
