I added the following line to my demo.pkg file:

"readme.txt"-"",FILETEXT,TEXTEXIT

The SIS file generated installs fine on a Nokia 6600.

However, when I start up the App. Manager, highlight my application and click "Options"->"View details", the following error is displayed:

"App. manager: System error (-20)"

"View details" works fine when I remove my FILETEXT line in the pkg file.

Any idea why this happens?
