I have Dreamweaver in DVD format and now i need about a auth code

@Vincenzo21776729dryq,

CS1, CS2, CS3 and CS4 activation servers are dead & gone. Even if you find an old installer, it's impossible to activate the software.

CS5 and CS6 are on life support. But they can still be activated providing you have the following:
1. your original media (disks or downloads) you received at purchase,
2. a legitimate serial number for that version, language and platform (Win/Mac) and if it was an upgrade, a qualifying serial number from an older product,
3. an older operating system that can support legacy 32-bit installers.

NOTE 1 : Creative Suite installers won't work on macOS Sierra, High Sierra or Mojave without terminal workarounds. See the help article below.

NOTE 2: Legacy Creative Suite will never run on Catalina, Big Sur or Monterey.  Nor will they be retrofitted for Win 11.  Only the latest Creative Cloud products are compatible with new operating systems.

NOTE 3: Legacy Creative Suite is discontinued & unsupported. Use at your own risk.
