How do I install apps. from Android market on my Android tablet if the market is telling me that there's no android devices associated with it? Just bought a cheap MID 7" Android 2.2 tablet. Tried opening the icon on the desktop that says Install Apps and all I got was a page with a heading of AppInstaller and then /mnt/sdcard. When I tried to put in the URL for the Android Market, it didn't work. When I used the browser to go to the Market page and install an app, I get the message that there's no Android devices associated with this device. Any ideas?
This Android Police post has a link to the current Market version (note it's the standard Market, not the Tablet version which only works on Honeycomb).  If you download it from your device you should be able to use your AppInstaller to install it from /mnt/sdcard/download/.
