Please download and install the latest version of Tansee software from here.
Additionally, ensure that you have installed the latest version of iTunes and verified that it is able to read your iPhone, iPad or iPod Touch.
(Mac OS does not require iTunes installation.)

Try using a different USB port.

The user must be a local admin. Tansee will not show up under a non-administrator account.
a. Right-click on the program shortcut or program .exe file, and click on 'Run as administrator'.
b. If prompted by UAC, click on 'Yes' to allow the program to run with full permissions as an administrator.
NOTE: If you are doing this while logged in as a standard user instead of an administrator, you will need to provide the administrator's password before the program will run as an administrator."

"When I launch the executable under any profile other than Administrator, a message appears stating 'iTunes is required, please install iTunes,' even though iTunes is installed and working properly. Running the program as Administrator resolves the issue."
