Well there is that many versions flying about Clint has got v188.8.131.52
and you have got v184.108.40.206.0 and I have got v220.127.116.11 LOL !!!
Right all joking apart there is only one version at the moment and it is the one I have !!!
And the way to to Use the virtual Drive :-
1> Make an Image of the CD with Clone CD you want to Mount !
2> Double click the My Computer Icon !
3> Right click on the Virtual CloneDrive and select Mount !
4> A window will open and ask you where the Clone CD image is just go to the folder where the image is and select it and just select open !
And there you are Mate the Virtual CloneDrive should now change to the Image you have just mounted and you can either Play, Install the program onto your Hard-drive or Make a copy of it to a CDR by using Clone CD !!!
In get rid of the Image from the Virtual CloneDrive just Right click on it and Unmount and it will be gone !!!
I hope this Helps you to understand it a bit better !!!
