Wrong version downloaded

I purchased a recovery CD download for Windows 7 due to a problem in setting up a dual boot. However I redeived the .iso file for Vista. Is there any way I can get the correct file without having to purchase a new file? I discovered the error when my Linux Mint grub display showed a Vista bood partition (sda1) and not Windows 7. If this is not possible, may I apply for a refund of the purchase price?
