Hello,

I am working on the 7650 and I have an application called MyApp.app whose version is 0.7 that I would like to upgrade with .sis files.

To do so I wrote this first upgrade .pkg:

#{"MyApp"},(0x02E8C2E7),0,9,0,TYPE=SISUPGRADE
(0x02E8C2E7),0,7,0,{"MyApp"}

"\Symbian\6.1\Series60\Epoc32\release\thumb\urel\MyApp.app" -"!:\system\apps\MyApp\MyApp.app"

And it worked all right: the installation of version 0.9 went okay.

Now if I try to upgrade from this version 0.9 to version 0.11 with the following .pkg

#{"MyApp"},(0x02E8C2E7),0,11,0,TYPE=SISUPGRADE
(0x02E8C2E7),0,9,0,{"MyApp"}

"\Symbian\6.1\Series60\Epoc32\release\thumb\urel\MyApp.app" -"!:\system\apps\MyApp\MyApp.app"

then during the installation at some point the following message pops up:

"Unable to install. MyApp required."

Could someone help me.

Thank you by advance
