  1. Q: When I download the EXE file with Internet Explorer, it asks “Do you want to run or save setup.exe (xxx KB) from”, if I click “Run”, I received an Error as following. 

A: This error occurs when you want to open (“Run”) the temporary downloaded EXE file from the permission restricted folder under C:\Windows. In order to run the EXE properly, click “Save” and then “Save as” to assign a directory (to allocate “setup.exe”) where you have the access permission. After that, you should be able to run the setup.exe file from the saved location as usual.
