Did you, do the following?
Go to the directory where you saved the Windows Memory Diagnostic executable file, mtinst.exe.
Double-click mtinst.exe to start Windows Memory Diagnostic Setup. Depending on your security settings, the File Download dialog box might appear when you run mtinst.exe. If it appears, click Open to start Windows Memory Diagnostic Setup. Other security dialog boxes might also appear. This can happen, for example, if you try to install Windows Memory Diagnostic from a Universal Naming Convention (UNC) shared folder. These dialog boxes are related to your security settings and not to Windows Memory Diagnostic. If you experience problems when you are trying to install Windows Memory Diagnostic, either be sure to run Mtinst.exe from your local computer, or review your security settings and the documentation included in your version of Windows.
Do either of the following:
Click Create Startup Disk to install Windows Memory Diagnostic on a floppy disk.
Select the floppy disk drive that you want to use from the list provided.
Insert a formatted floppy disk into this drive and then click Create. When the installation is complete, the Success dialog box will appear.
Or, click Save CD Image to Disk if you want to create a CD-ROM that you can use to start your computer.
Select a location where you want to save the International Organization for Standardization (ISO) 9660 image and then click Save. When the file has been saved, the Success dialog box will appear.
For more information about creating a CD-ROM that you can boot from, see the Note at the end of this section.
Restart your computer with the disk on which you installed Windows Memory Diagnostic (either the floppy or CD-ROM drive).
