• An application with the same package name is already installed on the phone.

• The current mobile phone operating system does not meet the system version required by the program package.

• The phone has insufficient storage space.

• The installation package has been damaged.

Solution:

• If "The application is not installed" is displayed, you need to check first. If the "Unknown Sources" option is not checked, applications that are not provided by the electronic market cannot be installed.

• Then double-click to open the removable disk, you will enter the page in the picture below, and then you need to find the .android_secure folder in the SD directory, as shown in the picture below, just in the red box Select the location and delete the file named "smdl2tmp1.asec".

• Finally, you need to turn on the phone again, and then find the security software installed on the phone, and then clean up the garbage. You can also use the phone’s built-in garbage removal program. After the cleaning is completed, Just re-download the APP.

• Check whether it is installed on this machine. If so, uninstall it directly.
