R-drive image Version 4.7 – The image file is not supported

Hello Everyone,
I am here with a problem with my R-drive image Version 4.7. I had a backup of important data of one of my hard drives. The backup was created using R-drive image 3.0 build 3037 version.
As I have already lost R-drive image 3.0 build 3037 version software, I used an R – drive image 4.7 build 4731 version which was available to me, As I was to get the backup this version says,
“The image file is not supported”
Can you tell me why this happened and how to get out of this? I am a beginning level computer user.
Please provide me with every single detail.
