Errors with software Installation

I am using windows 8.1.I have quick heal antivirus pro Installed. MY ProblemWhen i try to install Free Download Maneger(FDM) I have the error like following.

First Error IPresistFile:Save Failed Code 0x80070005 appears During the installation

Second Error When i try to run the software after installation. This Error appears

Note Images are not real screenshot, i have taken then from the Internet,But They depict the exact error as mine

Any and all help will be highly appreciated

What is the specific file that the installer is trying to create while you get the error message?
If the setup is able to install other files, maybe the NTFS permissions of the folder where it wants to install the file are messed up.
Is the installer being executed with elevated permissions? Please try to right-click the installer and run it with "Run as Administrator"
The second error is most likely due to the installer not being able to install all files.

I know this could also be a comment but I don't have the reputation to comment yet.
