Before you use Clean wipe on a 64 bit machine, u need to follow a different method instead of dorectly executing the program.
To run CleanWipe on 64-bit operating systems:
---------------------------------------------
1. Copy the CleanWipe folder to the target computer.
2. Open the CleanWipe folder and double-click the CleanWipe.exe file.
3. When you are prompted, browse to a location where you want the files to be copied and then click Start to extract the files.
If you click Start without selecting a location, the files are extracted to the Windows\Temp folder.
4. On 64-bit operating systems, CleanWipe must be launched manually. To launch CleanWipe, open a Command Prompt window (using Run As administrator). In the Command Prompt window, go to the folder that contains the extracted files. At the command prompt, enter RunCleanWipe to run the RunCleanWipe.bat file. Do not run the file from Windows Explorer.
Remember to click Yes in response to all prompts.
For more info have a look at read me.txt which will be there when you get Clean wipe.
U need to open a case with symantec to get the file.
