I have a hard disk with two partitions on it: C and D. All I have is 60 MB free on C:, which is a 14GB drive, but I have several GBs on D:, which is where I downloaded the software, but it does not want to install on D: even though I am telling it to do so. Can't the software install itself on D:, which has about 65 GB free? Thks. Then, assuming I get some good tips as to how to make the software install on D, is there anything special I need to know in order to merge D: with C: (the result would be a C: disk that would be about 100 GB in size)? Thks!
