FL Studio 8 installation fails with error message

Hi,
I am trying to download the FL Studio 8 version I bought, and I keep getting this error when I press “install” about 2 seconds into the install. I tried installing several times, but every time I get this ‘Error opening file for writing’ message. I tried installing after temporarily disabling my antivirus but this step too proved to be futile. I am running the installation with administrator privileges and I’m using windows 7 OS. I have attached a screen capture of the error received below. Can somebody help me to spot the trouble with this installation? Your help will be greatly appreciated.

Error opening file for writing:
C:Program FilesImage-LineFL Studio 8FL.exe
Click Abort to stop installation,
Retry to try again, or
Ignore to skip this file.
