What our users are saying

Thousands of customers around the globe rely on install4j for their mission-critical deployments.

“We left InstallShield and switched to install4j. We were up and running in one day, and our installation-related support calls almost disappeared after we released our new installer. When our customers are happier, we're happier. install4j has the features we require without the steep learning curve of the bigger packages.”

Brian Leach

“I just wanted to tell you how absolutely amazing install4j is. I am totally blown away and impressed at how easy it was. I had budgeted 10 days of fiddling around to get our product distributable with a native Windows installer and using your evaluation I did it in about 1 hour. I *immediately* grabbed my credit card and purchased install4j after that evaluation. Thank you so much for the incredible work you're doing.”
