Hi Naomi,

If SYSTEM.APP is in the application path it should find it. When you added it to the project, did it get flagged as excluded? APPs can be part of your project but must be flagged as "Excluded". Just for debugging purposes, you may want to include a code similar to this in your Form's load:

IF NOT FILE("system.app")
MESSAGBOX(SET("Path"))
ENDIF

or just include th path with the DO command:

DO data\system.app

If your client is only getting updated EXE's and you want to include the library in the EXE, include the source code for SYSTEM.APP into your project (system.prg, system.drawing.prg, etc...) and call DO SYSTEM.PRG instead.
