AVG 8.0 Installation error

I wanted to install AVG 8 on my PC, I download and run the installation but an error message appears:

Local machine: installation failed Local machine installation failed
Installation:
Error: Action failed for file avgssie.dll: file registration…. Error: Action failed for file avgssie.dll: file registration ….
Error 0x80070002 Error 0x80070002

I am stuck with this problem. Can somebody please kindly help me fix this so I can happily install AVG Antivirus on my PC?

Many thanks,
Sam
