XP install OK WIN98se fails

Neophyte with NSIS. Developed Install file. Carry file to XP on 3.5" floppy. Installs OK. Carry to WIN98se installs OK but when double clicking the Desktop ICON can't find the MyProgram.exe file. Same with START/ALL PROGRAMS/MyProgram.exe.

Any hints.

Thanks, Vern

Problem solved. It can he hell to be green at something. For those that may have viewed my problem, thanks.
