I’ve been hobbling along with Dreamweaver 8 on Windows 7 and now Windows 8, without the ability to save my FTP settings. It was fixed in the 8.0.2 patch, but the patch won’t install under Windows 7/8. My work around was just FTPing the file manually. Anyways, I found the solution to getting the patch applied in this forum post.
Basically, you manually run the patch using an unwrapped installer file, which you can still get here from Adobe. The trickiest part is that you have to open a Command Prompt running as Administrator. To do this, go to your Windows 8 Start page and start typing Command. You should see Command Prompt pop up eventually. Right-click and choose Run as administrator. Click Yes when prompted with a User Account Control message. Assuming you have administrator rights, the Command Prompt window should appear. (If you don’t, this exercise won’t work.)
So, unzip the patch file to an easy place to get to on your C: drive. In the Command Prompt window, navigate to the patch file directory and type:
msiexec /update patchpackage.msp
