I did what Eric suggested and also used the SharewearOnsale license key (although being warned not to do so as the program will not work).
After the license key was accepted and the program seemed to load successfully. Going to the now loaded program and selecting “Help” then “About” it indeed states the program was registered.
Going back to the programs start page I noticed that after the title “Batch Picture Resizer” was the following: ****Unregistered version****. Have not yet attempted to use the program but the Unregistered warning is disconcerting.
It would be reassuring if Eric had attempted successfully to use the program.
