If you do not want to try an alternate Install method,
just google: TPB
once there search for "MacDrive_v._18.104.22.168_Full___Keygen_by_CORE". It's a Windows program.
Be sure to read all comments on both pages, just in case, if the instructions for the download aren't completely understandable.
It's real easy, BTW.
Once installed, Macdrive WILL display you Mac Partition from your Windows Environment, and give you read/write access to your Mac Volume, just like it was another drive.
Please, post, if you decide to go this route, so that others in a similar situation, such as yours, benefit from this.
