Solved Options for reinstalling in vista x64

I am currently running 32bit Vista Home Premium. I would like to reinstall in Vista Home Premium x64. I have a product key for this. I want to do this legally. My computer is capable of 64 bit. I do not have a 64 bit instillation disk. My computer's manufacturer will only provide a 32 bit instillation disk. None of my friends have a 64 bit vista instillation disk or even run 64 bit Vista. I was just curious as to what options I have in order to perform this instillation.

Unfortunately your options are rather limited. Vista is an old Operating System; Seven has been out for a while and Eight is due in the near future. Vista will not even be supported shortly. The ususal method to get a Vista DVD is to contact your computer manufactuer and they will send it to you for cost. Since Vista is old, this option is not always available. Any downloads that you may find on the internet are most likely illegal and contain virus and other surprises that you would not like. In addition, the use of illegal downloads could create legal problems for you, so that is not an option.
You could create a universal Vista DVD, but even then you need a Vista DVD, 64 bit, but any version. http://jimcofer.com/personal/?p=6119
The only other option that I can think of is to buy an upgrade Seven version. The cost is relatively high, about $125.00. I am sorry, but unless others think of an option, you have no other alternatives. Good luck

Thanks for the post Richc46.

I thought I would add some of my findings to this post before marking it as solved.
From what I have found there is no legal .iso download for vista, mainly because it is so old. However, I unintentionally found a solution from another thread I posted. There is a legal download (found by Slammer) for the instillation files here.
There is an instructional video on how to turn these files into an .iso disk. It's not to hard either. The only tricky part is the program used to create the .iso disk has no GUI. It's all cmd interface. The instructional video explains how to create a x86 disk; however, this doesn't cause any problems because it is the same for x86 and x64. The very last 'phrase' of the command to execute the program is the name of the .iso you are about to create. In the video it says something like vistaX86 in this part. This worried me at first because I thought it was going to make a x86 disk. Just type in whatever you want here though. It's just the name of the file.
I did this and it successfully created the .iso. However, when I burned it to a disk using the freeware imgburn the disk did not work. This could be from bad burn. I also tried booting the .iso in oracle virtual box. It gave an error, but a good error. It basically said that it could not boot from the .iso because the .iso was 64 bit. Virtual box is a 32 bit program, so it may not be able to load it for that reason. I don't know for sure because I didn't explore the issue.
I found a friend that had a 64 bit instillation disk, so I reinstalled with that.
In summary. I think the .iso created from this program works; however, I'm not sure. If someone is looking to reinstall vista in 64 bit from 32bit and they have a legit product key, I would check this link out.
