Boot Camp drivers not compatible

I am having problems installing Win7 Ultimate. I followed the directions of BC Assistant, downloaded the drivers and the needed files to a 16GB flash drive. Everything was okay until the drivers installation. The message said the drivers were not compatible. I did point where the drivers were located in the flash drive to no avail.

The drivers were downloaded by Boot Camp Assistant, so I assume they should be the correct ones.

At this point I don’t know what else to do. The 200 GB Boot Camp is partitioned is in the main drive and ready for Win installation.

Any suggestion of my next step would be appreciated.
