I was receiving this Visual C++ Runtime Error in Adobe Dreamweaver CS4 and after hours of work, I finally solved it. At first I tried uninstalling and reinstalling the whole Master Suite. This didn’t solve the problem and I was growing tired. After realizing the error didn’t occur when I logged in as a different user I looked at the registry. I exported then deleted the following Registry folder:
All the CS4 apps went back to their default state and Dreamweaver opened correctly. If you encounter this error, before you reinstall the whole suite, give this a try. Just make sure you export a copy of the Adobe folder before you delete it.
