How to install a software program from an ISO file


An ISO file, also known as an ISO image, is a file that contains all of the installation files for a single program. Some software, especially larger ones, is sometimes available as ISO files, including Microsoft Office and the Windows operating system. How you install an application from its ISO file depends on the version of Windows you are using.

In Windows 10 or 8.1, you can mount the ISO file as a virtual drive and install the software from there. If you’re still using Windows 7 (you shouldn’t be), you’ll need to download a utility that can mount the ISO file for you. You can also burn the ISO file to a disc or copy it to a USB drive and install it from the CD or drive. If you download Windows 10 as an ISO file, you will need to burn it to a bootable DVD or copy it to a bootable USB drive to install it on your target computer. Here’s how to install an ISO image on Windows.

Mount the ISO file in Windows 10 or 8.1

Download the ISO file, then open File Explorer and right click on the file. In the context menu, select the Mount command.

Sometimes a third-party program can disable the built-in Mount command so that it does not appear in the menu. If so, you will need to reset your default program to restore control. In Windows 10, go to Settings> Apps> Default apps and scroll to the bottom of the page. Click it Set default values ​​per application connect. In the list of applications, click on the one for Windows Disc Image Burner and click Manage.

Burn ISO file to disc

Another option to install a program from an ISO file is to simply burn the file to a CD or DVD, or copy it to a USB drive and install it from there. This is a useful method if you want to store the program on a disk that you can install in any version of Windows. You would also do this to install Windows from an ISO file on a clean machine.

To burn the ISO file to a disc, insert a blank CD or DVD into your PC’s disc drive. Open File Explorer or Windows Explorer and right click on the ISO file. In the context menu, select the Burn a disc image order.

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 installation file as it appears in File Explorer or Windows Explorer.

Another option that gives you the option of burning the ISO to disc or copying it to a USB drive is the Windows USB / DVD Download Tool, a free utility from Microsoft. This tool copies the contents of the ISO file to a CD, DVD, or USB drive so that you can then install the program from the disc or USB drive, which becomes bootable.

This is a good method if you want to install Windows 7, 8, or 8.1 on a clean computer or as part of a dual-boot setup. Microsoft no longer offers this utility on its website, but you can still find it on other sites, including FileHippo and Major Geeks.

After downloading the Windows7-USB-DVD-Download-Tool-Installer.exe file, right click on it and choose it Execute as administrator option. Once the installation is complete, launch the tool and then locate and choose the ISO file you want to burn. Click Next, then choose a USB device or DVD.

If the USB flash drive still contains data, it will be erased. Click on Erase the USB stick to make room for Windows files. After the files are copied, the tool will tell you that the bootable USB device has been 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 Start Burning. The tool will notify you once the DVD has been burned successfully. You can now use your bootable DVD to install the program.
