Can't Install Arduino Because of Arduino Builder

I have tried to install Arduino on my Windows 8 laptop multiple times and it keeps giving me an

Error opening file for writing:

C:\Program Files(x86)\Arduino\arduino-builder.exe

I have uninstalled Arduino. I have also tried to manually delete the arduino folder, but i still recieve an error.

It says i need administrator permissions to perform this action. I am the only user on this pc and i have administrator permissions.

I really need to get this problem sorted. I use Arduino for my quadcopter and my 3D printer.
Any help would be greatly appreciated.

Don’t install it in ProgramFiles. Or if you insist on installing there then you will have to run as administrator.

Try downloading and using the "Windows ZIP file for non admin install" from: http://www.arduino.cc/en/Main/Software

That worked!! Thank you both for your timely response. I was starting to sweat!!
