How can I use Adobe Dreamweaver CS5 from my USB disk?
I believe it exists an Adobe Dreamweaver CS5 portable edition. Google it;)
did you try MojoPac or ThinApp? Did any of them let you use the program as a portable app? let us know what worked for you. Thank you!
Since Adobe installs a lengthy list of System files and Registry entries I'm not sure that's possible. Adobe AIR for example uses absolute paths to address required files and it's probably the same for other Adobe programs.
Your best chance is to install a portable Windows Environment to your USB Disk like MojoPac and install Dreamweaver within there.
