In this age of internet, frequently it happens that your system gets infected by a virus or spyware and your antivirus software is unable to detect and remove it. Now you want to install another antivirus program. To do this you double click the executable file to run the setup of the antivirus program but either nothing happens or initial splash screen automatically disappears after a second or two before you can proceed any further with the setup. And to your frustration it happens repeatedly. Don’t worry, here is a solution to this problem, just follow the instructions given below..........(I will use Avast antivirus setup as an example)

1. First, you must have the following information-
a. the exact name with correct spelling of the setup(executable) file you want to run (like ‘setupeng’ in our example case) and
b. the exact correct path of the setup file as c:\softwares or if the setup file is in a flash(pen)drive or optical media (CD, DVD etc) then you must know the drive letter (E:\, F:\, etc) for that drive and path to the setup file (for example our setup file was in a pen drive with a path H:\setups). You can view and note the above information through windows explorer.

2. Now having this information, restart your computer and press F8 key repeatedly at restart to bring the windows diagnostic startup screen. Select ‘Safe mode with command prompt’ option and press enter. After windows starts, command prompt opens in a window, now if you are well versed in using command prompt then just navigate to the path of your setup file and press enter and it is done, but if not then follow these steps- first type the drive letter in which your setup is present like this- ‘E:’ (without quotation marks and assuming that E is the drive where setup is present) and press enter-
now if the setup file is in the root of directory then just type the name of setup file and press enter. But if the setup file is in a folder or subfolder in drive then use ‘cd’(change directory command to navigate to the destination folder. For example if the setup file is in subfolder named SECURITY, which is inside the folder named SETUPS, which is ultimately in the E drive then first type E: and press enter then type "cd setups" and press enter then type "cd security" (Without quotation marks) and press enter then type the name of setup file and press enter and the setup should run successfully now..............
Good Luck & happy computing.
