Okay, well I am not sure I fully understand your question, but I will walk you through the basic steps on how to update your tablet to the newest releases and hopefully that will achieve your desired results! If you want, try phase 2 first and see if that fixes it. If it doesn't, start at phase one and work your way all the way down again.
Phase One:
First, go to the device manufacturer's download page and get the firmware and AppsLib downloads. You can find the sites you need
HERE, and
HERE.
Once you have the two files downloaded, you will connect the tablet to the computer via the USB cable. Once windows finishes recognizing the device, go to My Computer and open the tablet's root folder by double clicking the tablet's icon in My Computer.
Next, drog and drop the FIRMWARE file (NOT the AppsLib one yet) in to the Archos Root folder.
Right click the USB icon in the bottom right of your desktop and click on the selection that ejects the archos tablet, once it is properly ejected, unplug the USB cable from the tablet.
The tablet should recognize the file automatically after ejecting and you just need to click update after connecting the DC charger cable to the device. When the process finishes, the device will restart and you will go through the installation wizard again.
Phase Two:
After that is done, hook the tablet back up to your PC via USB and browse to the tablets root folder again. From there you should see a [DOWNLOAD] folder, open it.
Verify that the AppsLib download is an apk file and not a zip file. (right click it, click properties, the window that pops up will say type of file...) If it is a zip file, change the end of the name to .apk and put it into the [DOWNLOAD] folder.
Safely eject the tablet again
Open the tablets file manager and go to the download folder, tap twice on the Appslib.apk file and follow the on screen instructions!
Good Luck
