MediaBinWebClient8.0.0.0 Installation Problem

System

Hello Dev Users,

I am new to mediabin, and ask for help.

I've succeed in installing Virage MediaBin Asset Server 8.0.1.1. and it was fresh installation. Since I could not find WebClient 8.0.1.1, I tried to install WebClient 8.0.0.0 instead.
But while installing MediaBinWebClient8.0.0.0 (Maybe it is Virage MediaBin Legacy Web Client on Release note), I got error message regarding IIS.

Error message :
ERROR: Getting pointer to IIS Root Container failed.

Installation environment:
Fresh Installation.
- OS: Windows 2008 R2 Enterprise
- DB: Oracle 10g express
- IIS : IIS 7.5

Actually, I am not sure whether installing MediaBin Legacy Web Client on Window Server 2008 is possible.
I've checked release note, but it was unclear.

Any advice will be helpful for me.
Thanks.
