I took the last version from my old computer (XP 32 Bit) and copied it onto the desktop of my new machine. I have always used Bright as a desktop program and not as a PSP plugin. the version I copied worked fine before.
The folder contains two files,
A Bright Windows Batch File with the 'gears', 1KB in size.
A Bright Application File, 108 KB in size.
I place the 24 Bit converted file from PSP in the folder and run the Batch file. It doesn't seem to work any longer.
I went 64 Bit to 'future proof' my computer.
Thanks for the assistance adlabs.
