"Question" I think charging $7 to cover any re-downloading after 30 days on a $40 product is outrageous, but there you go.
This is the "Third Party" that is charging this. If you Copy the download to a CD then there is NO need to pay the extra for another download within 30 days. Besides what is one going to do after the 30 days are up. buy another copy. NO way that is why one needs to burn the CD of the download file.
"Question" I also hear that if you replace your computer, or it crashes, and you're already using your 2 installs, you're out of luck (is this true?).
You can install FTM on two machines with out questions. This is normally one desktop and one laptop. But do not get the extra "Free subscription" time. You can install FTM as many time as you want or need to on the same machines, or even a new one as long as you remove it from the "OLD" machine. Ancestry do not have much of a tracking method of installs since they do not use Key Codes. You would need to register each install to get the access to the subscription account.
Since I do a lot of testing of OS, hardware and other programs, I have install FTM on many machines many times. I have one machine with 4 versions of FTM on it.
