  • Click the Browse button and navigate to your CD or DVD drive.
  • Double-click setup.exe.

Step 2 – Copy The Setup Files To Your Hard Drive

Windows can often become confused with CD files, making it a wise decision to put them on your Hard Drive. To do this follow these steps:

  1. Open up “My Computer”
  2. Browse to the CD Folder
  3. Select all the Office 2007 files
  4. Copy them by pressing CTRL+R
  5. Click onto an available hard drive
  6. Create a new folder
  7. Paste the files using CTRL+V

This will put the installer files onto the hard drive of your system, which should help your system better read the files it requires to run.
