Thread: Unable to install Mozilla Firefox in Windows 7

Just now few days ago I upgraded PC and installed Windows 7. But problem is when I try to install Mozilla Firefox 2.0 installer loads and then ended automatically. This occurs every time when install browser. So please give me any suggestions to solve this problem. Any help will be appreciated.

Installer file from which you are installing browser may be defective or installation files are not downloaded totally because of internet fluctuation. So try downloading new installer file and install it. Downloading new installer file for browser will solve problem.

Run installer file in compatibility mode and see if browser installed or not. All versions of Windows released after XP have compatibility mode. To run installer in compatibility mode, right tick on installer and choose properties. Pick "Run the application in compatibility mode" and choose XP. Save and apply settings and then see if browser installed or not.
