You must do a clean install of 64bit. You cannot make a 32bit into a 64bit. You will have to format and reinstall.

Windows 7 Ultimate SP1 64-Bit

You haven't given us your computer specifications other than you're running Windows 7.

If you haven't got a 64-bit-capable processor you won't be able to install the 64-bit version of Windows.

There is no upgrade path from 32-bit to 64-bit Windows, it will have to be a clean install and the best way forward, after you have copied out or made back-ups of the data you need to save to external media, have a look at this tutorial at the link below.

Do a Clean Install with a Upgrade Windows 7 Version

All the installed programs/apps will have to be reinstalled so be sure to save the activation keys where applicable and be sure to post back with any further questions you may have and to keep us informed.

Where did you get the 64-bit Windows 7 installation DVD?

If the Windows 7 install disk is one you burned yourself it may be a bad burn and needs to be done again, if so this would be the first thing to try.

Use the free ISO burner at the link below to burn another at a speed of no more than 4x and select to let the program to verify the disk before it finishes.

You may also need to confirm the ISO integrity.

Again: where did you get Win7?

How do you plan to activate it?

Agreed - if you got it from a legitimate source (Technet, MSDN, or the Microsoft Store) you should have the ability to compare the ISO you downloaded against the hashes available on those sites (CRC, SHA1, MD5 sums, etc) to verify if what you downloaded is valid and matches the ISO on the source.

If you downloaded it from anywhere else, be aware that doing so is actually a violation of copyright laws in the US, Canada, and most (not all, but most) European countries.
