The .ISO file X15-65805.iso is for Windows 7 Professional 64-Bit. Professional will only upgrade properly if you have Vista Business edition installed. However you can verify this for certain by using the Hash and CRC values I listed below for Professional.
Dell Genuine Windows 7 Professional OEM DVD ISO Overview. Windows 7 Professional is the new operating system developed by Microsoft. Microsoft Windows is considered as the most used and easiest Operating System around the world. I've got a Dell Latitude E6410 Laptop with a Windows 7 Professional OS installed on it which needs a fresh win install on it. I would like to download a win ISO since I haven't got the windows cd but I can't download it from the Microsoft website because is a OEM version I think.
Profesional = SHA1: 50127304441A793EE51B3F501289F6599A559E9F ISO/CRC: 502C42C1

Verify the .ISO file you downloaded is not corrupt:
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 cancle 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.
These 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. However they should match those I've posted.
