Installing a Software Program From an ISO File

    Installing a Software Program From an ISO File

    The way you install a program from an ISO image depends on the version of Windows that you use. This is How you install an application from its ISO file on a Windows 10, 8.1, and 7 program.

    An ISO file also referred to as the ISO image, is a file that contains all the software installation data. Some software programs, especially large ones, are often made available as ISO files, like Microsoft Office and Windows. The way an application is installed from its ISO file will depend on the Windows version that you are running.

    In Windows 10 or 8.1, the ISO file can be mounted and configured as a virtual drive. If you still run Windows 7, you’ll have to download a utility that can install the ISO file for you. The ISO file can also be burned on a disk, copied to a USB drive, and placed on a CD or on a drive. You will need to burn it into a bootable DVD or copy it onto your booting USB drive when you download Windows 10 as an ISO file. Here’s how to install a Windows ISO image.

    In Windows 10 or 8.1 install the ISO file.

    Download the ISO file, and open File Explorer, click on the file right-click. Pick the Mount command from the pop-up menu.

    mount file

    Often a third-party program will disable the Mount command that is built-in so that it does not appear in the menu. If so, your default program must be reset to restore the instruction. Go to Settings > Applications > Default Apps in Windows 10, then scroll down the list. Select the Defaults Set connection for the app. Click the Windows Disk Image Burner app list and click Manage.

    default program

    Click the name of the third-party program and change it to Windows Explorer.

    Return to File Explorer and right-click again on the ISO file. Mount should be reflected in the menu now. The Mount command opens a virtual drive that is available in the sidebar File Explorer from which the program can be mounted. You can find a setup.exe file or a similar file to install the program on this virtual drive. To install it, double-click the file.

    open file

    After the installation has finished, open the This PC folder in File Explorer so you can see all your disc drives. Right-click on the virtual drive. (It will likely have a drive letter of D or E, depending on your configuration). From the pop-up menu, click the Eject command. This removes the virtual drive, though your ISO file is still alive and well.


    Mount the ISO File in Windows 7

    The Mount command is available only in Windows 8, 8.1, and 10. If you’re running Windows 7, you can instead turn to a free virtual drive utility, such as Virtual CloneDrive. After installation, open Windows Explorer in Windows 7 and right-click the ISO file you wish to install. From the pop-up menu, click the Mount (Virtual CloneDrive) command.

    The virtual drive is created. A small window pops up asking if you want to run the setup file or open the folder for the virtual drive. Choose the option to run the setup file.

    run file

    The installation then proceeds. After the program has installed, right-click on the ISO file in Windows Explorer and click Unmount from the pop-up menu to remove the virtual drive.


    Burn the ISO File to Disc

    Another choice for downloading an ISO file is to simply burn the file on a CD or DVD and mount it on a USB drive. It is a useful way to store the software on a disk that you can run on any Windows version. You can also install Windows on a clean machine from an ISO file.

    Install a blank CD or DVD into a disk drive of your PC to burn the ISO file onto a disk. Right-click on the ISO file and open File Explorer or Windows Explorer. Pick the Burn disk image order from the pop-up menu.


    burn disc image

    The Windows Disc Image Burner tool pops up and should point to your CD/DVD drive. Click the Burn button to proceed. The ISO file is burned to your CD or DVD. Your disc drive may then open so you can remove the disc.

    Depending on your installation settings, you can then install your program from the disc automatically by placing it in the drive of a PC or by double-clicking the setup file as displayed in File Explorer or Windows Explorer.

    Download tool for Windows USB/DVD

    The Windows USB/DVD Download Tool, a free Microsoft tool, is also an option that allows you to burn or copy the ISO to a USB disk. This tool copies the contents of the ISO file to a CD, DVD, or USB drive to install the software on the bootable disk or USB drive.

    This is a good way to install Windows 7, 8, or 8.1 on a clean machine or in a dual-boot configuration. Microsoft no longer has this tool on its website, but you can still find it on other sites such as FileHippo and Big Geeks.

    After the Download-Tool-Installer.exe file for Windows7-USB-DVD, right-click and choose Run as the Administrator option. When the installation is completed, start the tool then navigate to and pick the ISO file you want to burn. Then pick either a USB device or a DVD, click Next.

    choose media


    If you choose USB, the next screen asks you to insert the USB media. If you have more than one USB drive plugged into your PC, make sure to choose the correct one. Click Begin copying to copy the file onto the drive.


    If the USB drive still contains data, it will be erased. Click Erase USB Drive to make room for the Windows files. After the files have been copied, the tool will tell you that the Bootable USB device was created successfully. You can then use your USB device to install the program.


    If you choose a DVD, insert a blank DVD into your drive and click Begin burning. The tool will inform you once the DVD has been successfully burned. You can now use your bootable DVD to install the program.
