Error occurred when tried out the Qtracker autoInstaller

Hi,
Today, I received the following error message when I was trying to install Qtracker Autoinstaller but the installation failed. I tried to reinstall the setup to fix this problem but the error remained. The installation stopped at the end of stage and threw this following error. Can I get the resolution?
I would be grateful to you for any kind of assistance.

Installation failed!
The process cannot access the file because it is being used by the process.
