Insufficient space when downloading Go Launcher EX?

> **Possible Duplicate:** > [“Insufficient storage” when trying to install anything on htc thunderbolt](https://android.stackexchange.com/questions/23010/insufficient-storage-when-trying-to-install-anything-on-htc-thunderbolt) When I download the Go Launcher Ex App from the play store, it downloads okay but shows "Insufficient memory"(The internal memory) when it tries to install it. :/ It is a 6 or 7Mb app, where as my internal storage has 25Mb free and the SDCard has almost 1Gb free space. I don't get what the problem is. My Android version is 2.3.6 if that helps. Would really appreciate it if someone helped me. :)
