I have an issue with Internet Explorer 9 and Design Review 2012 on a machine with WIndows 7 64bit. When I try to open a DWF file it asks me what I want to do. Open, Save, or Save as. Then it asks me to Open, Save or Cancel down at the bottom of my window. When I click on open it opens the file by actually opening Design Review program and not inside the browser. Can this be fixed?
I am having this same problem. Did you ever find a fix for this issue? The plugin works fine after I install it but after I reboot the machine it does exactly what you mention. If I uninstall and reinstall it will work again until I reboot.
I found a work around for this problem. It seems like it is a firewall related issue but I'm really not sure what it is specifically. When I opened up the firewall completely it worked fine. I found the workaround to be running the website in 32 bit Internet Explorer instead of the default 64 bit. I just made a shortcut on the desktop to the website directing it to open in 32 bit IE everytime.
