Unfortunately, ADB is only able to push the apk from your PC (running ADB) to the tablet. So you will need to copy the apk from the tablet to some directory on your PC and then do: "adb push [Path+filename of apk]". Also, since this is an Amazon Appstore app, you will need to push the apk for it as well using the same mechanism as some apps require that running before they will run. I hope this helps you.
BTW, this would mean the following steps:
- Install ADB on your PC and ensure that your HD is in development mode. Connect the HD to the PC and type "adb devices" - it should respond with a unique serial number if it sees your device correctly.
- Find a copy of the apk that you are trying to install and copy it to your PC in some location, say "c:\temp". Also do the same for the Amazon Appstore apk.
- Type "adb push c:\temp\<app>.apk". This should install it on the HD.
