I also just found out something else that you guys may know, but I didn't learn until now. When I purchased my Office 2013 I got a backup DVD just in case I was not able to download it again for some reason. I thought it would allow me to install either
the Click To Run version or the MSI Installer version. It would except for one thing. The Product Key you get with your order for the downloadable version only allows you to install the Click To Run version unless you get a second Product Key with the DVD.
If you get it straight from the Office Store just click the green button and get that second Key. Now you can install it in either flavor. But if you are like me, I got it through a special offer through my company and I ordered a backup DVD which came from
the Office store because it has the sticker inside that says if you want the MSI installer version you have to get that second Product Key, except one thing: You can't get a second key unless you bought it straight from the Office store. So basically, I have
a backup DVD that has the entire MSI version on it, but I can only use it to install the Click To Run version because I didn't have any way of getting the second key without going to the Office store and buying a full retail version. So, to sum up: Even if
you have a backup DVD, if you didn't get it at the official Office store with a second Product Key then you are only able to use the DVD to install the Click To Run version. It doesn't make any sense to me why you can't install it as long as you have at least
one key. Just because you found a good deal why penalize you? And why bait and switch you by making you think you have a true backup that works like a DVD should when it is no different than using the tiny setup files that you downloaded when you first installed
it. To be fully forthcoming they should give you a DVD with just the tiny setup files and nothing else. But no, the DVD has the entire full MSI installer version even knowing that you would not be able to use it. Oh well, just thought you might like to know,
because in this time of crisis when we are all looking to our emergency backups to get back up and running, this little gem of knowledge was quite a surprise and letdown.
