The last three days of the time is spent on re-update system, things purely man-made, it is summarized below for future reference.
1. Install the program should not be installed after the software is installed in the same file folder, easy to manage, and the two folders are not used Chinese name.
2. Be sure not stupid enough to directly modify the name of the folder.
3. Remove software to uninstall the software first, and then delete the installation software.
4. The installation process has been a problem, you can try to re-create a new directory and then try to uninstall the core of the problem may not have a clean uninstall.
