I have never been able to install updates on CS4. I keep getting an error message "Run this update again". I've tried turning off the firewall, but this makes no difference. I am using Windows 7 on my PC. Help!
What products? Per se there is no reason why updates should not apply just because of Win 7, but just like today in Cs6, back then there already were conflicts where product A had been updated but this prevented product B from running any updates. Manually downloading might be a start, but there's a chance you may have to reinstall from scratch and start over after running the Creative Suite Cleaner Tool
Many thanks for your reply. I did uninstall CS4 and re-installed it again. I'll try running the Creative Suite Cleaner Tool. I'm not an expert with photoshop, so I would manually download the update directly from the this website?
