How to use ISO downloads
Many of the downloads from software.caltech.edu are ISO files, which essentially contain all the files and folders of a CD/DVD. To use an ISO file, you have several options:
Mount an ISO onto a virtual drive
- In order to mount the ISO on a Windows computer, you will need to use a third party ISO mounting application. Some options include:
- Virtual CD-ROM Control Panel (Windows XP, Vista, 7 compatible): http://www.microsoft.com/en-us/download/details.aspx?id=38780
- Virtual Clone Drive: http://www.slysoft.com/en/virtual-clonedrive.html
- Magic ISO Virtual CD/DVD-ROM: http://www.magiciso.com/tutorials/miso-magicdisc-overview.htm
- Review the instructions or Read Me files for these tools for directions on how to install the software and mount an ISO.
- Mac OSX will automatically mount an ISO by double-clicking the ISO file itself.
- Once the ISO is mounted, you can browse through all the files contained within the ISO to begin your software installation.
Create/burn an install disc
- You will need CD/DVD burning software installed on your Windows computer in order to create an install disc. If you do not have disc burning software already installed, some options include:
- ImgBurn: http://www.imgburn.com
- Power ISO: http://www.poweriso.com
- When burning your disc, be sure to select the option to create disc from image, or burn image. Do not simply create a data disc, which just copies files and folders to disc.
- Windows 7 and 8 have the ability to create discs from an ISO without any third party tools:
- Locate the ISO file that you want to create a CD/DVD from.
- Right-click on the ISO file and select Burn disc image.
- Select your Disc burner on the next screen and click Burn.
- Mac OS X can also create install discs without any third party tools:
- Launch Disk Utility, located in Applications > Utilities.
- Under the Images menu, select Burn.
- Select the ISO file that you want to burn.
- Make any changes to the options, and click Burn.
- Once the CD/DVD is created, you can use the disc in any computer with a CD/DVD drive and install software directly from the disc.
Extract the ISO contents
- To extract ISO contents and save them to your Windows computer, you will need a third party tool. Some options include:
- Once the ISO contents have been extracted, you can browse through all the extracted files to begin your software installation.
