I created a 64 bit DVD.  I tried launching setup.exe from the DVD, which rebooted the computer and started installation, and stuck at 34% for several hours.

I then rebooted the computer, and through F12 launch menu, chose to boot from the CD/DVD.  It still booted up Windows 7, then went through the same process as before.  The second time I eventually let it run and it took 5 hours to reply it couldn't install.

There was no option for clean install or upgrade.

Clean install?? What consumer wants to lose the contents of their hard drive, files, settings, etc to upgrade their OS?

Hello JamesHydeJr,

If your installation is hanging then it may be that your installation is corrupt and you may be missing some files.
Did you verify the Sha 1 hash for the ISO you downloaded?
Also, you will need to verify the szie fo the downloaded file. Many errors of this type are caused by a corrupt download or a bad burn of the media.

Download Windows 8 Release Preview from the following location:
http://windows.microsoft.com/en-US/windows-8/download

English

64-bit (x64) Download (3.3 GB) Sha 1 hash — 0xD76AD96773615E8C504F63564AF749469CFCCD57

32-bit (x86) Download (2.5 GB) Sha 1 hash — 0x8BED436F0959E7120A44BF7C29FF0AA962BDEFC9

Product Key: TK8TP-9JN6P-7X7WW-RFFTV-B7QPF

To verify the Sha 1 Hash:

(Information about HashCalc from Andre Da Costa)
Download and install SlavaSoft's HashCalc
HASH, CRC, AND HMAC CALCULATOR
http://www.slavasoft.com/hashcalc/index.htm

For Windows .ISO file just place check marks in the SHA1 and CRC32 boxes.

In the main HashCalc Window the 'Data format' box located in the upper left should be set to "File"

In the 'Data' field click on the ... box located in the upper right and then click 'Cancel' if you get an 'Insert Disk' window pop up.

After you click 'cancel' you should see a 'Find' window. Use this to navigate to the folder where your .ISO file is stored and click on the file.

You should now see the .ISO file you clicked on listed in the 'File name' box located near the bottom of the 'Find' window.

Now click the 'Open' button. The Data field should now show the directory/folder path and the name of the .ISO file you selected.

With only the SHA1 and CRC32 boxes checked (Do not place check marks in any other boxes as this can slow down the time it take to calculate the values) click the 'Calculate' button located at the bottom of the main HashCalc window.

It will take anywhere from 30 to 60 seconds for the calculation to complete and the SHA1 and CRC32 data values to be displayed.

The reported values are not case sensitive, so a lower case 'a' is the same as an upper case 'A' as far as the results are concerned and should match what I have posted.



Let us know if this helps.
