I think a typical scenario that causes this problem is when you upgrade apps and some somewhere down the upgrade process the Dalvik cache and other folders art not cleared.
Watch fix the problem for me was apps2sd which was already installed and what I did was using a broken appcleaner and cleared all the Unwanted files turned out to be somewhere around seven hundred plus MB.
That fix the problem

Difficult so say what the cause of your problem is. Obviously not your sd card and memory
One cause may be the google Play Store app.

Did you try:
1. Tap the Settings icon, select Apps > All > Google Play Store > Force stop / clear cache
2. Tap the Settings icon, select Apps > All > Google Play Store > Remove all updates (you can re-update later)

Edit:
From the quora website:

Possible/Common causes of “Application not Installed” error

Insufficient storage space: Your storage space may have filled up with no more space to accommodate new apps.

Corrupted app or apk file: This is most common with apps downloaded from outside Google Play Store. The app is either corrupted or incompletely downloaded or copied as the case maybe.

Incorrect app install location: Some apps are meant to be only installed on phone memory while some others can be installed on both phone memory and SD card. Trying do otherwise with the former can bring up this errors.

Installation on a mounted SD card: Maybe, your SD card is mounted on a laptop or elsewhere. Trying to install anything in this state will result in errors because the SD card is inaccessible.

Corrupted storage (Phone and SD card): This is probably the most common cause of this error. If the storage of your device is corrupted, any app installation will be impossible.

Apk signature/certificate clash: Installing another version of an app (with a different signed certificate) on the same device will probably result in this error. Installing an unsigned app could also result in this error.

App permission errors or temporary OS glitches could also bring about this error.

Possible Solutions of “Application not Installed” error

Reboot the phone: In times like this, first thing to do is to reboot your device. Or just shut down, remove and reinsert your battery.

Make sure to uninstall any apps you don’t use to free up space, also uninstall previous versions of the same app currently installed on your device.

Double check the apk files you download and be sure they were completely copied or downloaded.

Try resetting app permissions by going to Settings >Apps>All>Menu key >Reset application permissions or Reset app preferences.

Change app installation location to Automatic or Let system decide.

Make sure your SD card is not mounted or connected to a PC or elsewhere.

For worst case scenarios, format your SD card – copy it’s contents somewhere else for backup and format.

The last solution would be to totally wipe your device. Either by doing a factory reset under Settings or by doing a full wipe in recovery mode.

Was having the same thing when trying to export a signed package from Eclipse. I resolved the problem by setting a 'key' in the keystore with a long lifetime - when it was just a year then the problem occurred. Also found that it was a good idea to 'Uninstall for all users' if the app is already installed.
