hmmmmm .... probably because his instructions for the PNG2PAA.BAT file location and execution seem to be mixed up, 2 different methods there.
If you have done the "ascociate PNG with PAL2PAC.EXE" bit, then I suggest when you Right-Click, it should work when you select OPEN at the top of the menu.
- Take a copy of the png2paa.bat
- Place the copy in directory;
C:\Documents and Settings\USERNAME\SendTo
If you can't see that "SendTo" directory you need to un-hide files.

Now when you Right-Click the 12 files, move to SENDTO and then select the PNG2PAA.BAT
Should do the same as Allie intended.
