Error while installing K – Lite CodecPack

I linger to install the most up-to-date version of the K – Lite codec pack 8.2.0 in both the 32 and 64 bits, using the Windows 7 x 64 Home SP1 OS, unfortunately, I cannot set off the installation process. Instead an error showed up as displayed in the picture below:

Error
Zugriff verweigert.
An Error Zugriff verweigert appears and I wonder what this foreign language means.
I hope I could be able to resolve this as soon as possible. Please help!
