Some prerequisites of MATP 5.5 not found while installing Office 2010 RTM

Hello.
I tried to install Microsoft Assessment and Planning Toolkit 5.5 with Office 2010 RTM (Bulgarian) edition.
But then I am getting the following error.
Please see below.

Installation stops from proceeding.
I don't understand why the installation still "talk" about "Office 2010 RC" on the Prerequisites when RTM was out long before the release of MAPT 5.5. I need to know about this.
Please answer.
Thanks a lot.
Error:
