Installing AutoCAD Architecture 2005 on Windows 7, Windows 8 and Windows 10

Installing AutoCAD Architectural Desktop 2005 (ADT 2005) on Windows 7, Windows 8, Windows 8.1 or Windows 10 32bit or 64bit can be very easily defined in these short steps…

IMPORTANT NOTE: Autodesk says that it no longer supports older versions of AutoCAD and, as part of that policy, no longer routinely provides activation codes for these releases. However, it is still possible to get your AutoCAD activated, we document all of your options here

1. Obtain your copy of the Longbow Converter here
2. Copy your AutoCAD Architectural Desktop 2005 installation CD to your hard drive, to a folder path c:\Autodesk\adt2005
   1. If you have more than one CD, simply copy them all directly over the top of the first CD, basically, overwrite all CD1 files in your previously copied c:\Autodesk\adt2005 folder with CD2
3. Start the Longbow Converter tool
   1. Select the 2nd tab named “Old AutoCAD installer Reviver“
   2. Pick the c:\Autodesk\adt2005 folder
   3. Click the “Run Old Installer” button.
      1. Read and understand all the prompts before pressing OK. Once the setup starts, stop and read the next step…
4. In the setup program, navigate through each setup dialog as normal, with these exceptions…
   1. When you click the Install link from your setup you may see a dialog box appear saying – “This program has compatibility issues” – simply check the “Don’t show this message again” and then click the “Run the program without getting help”.
   2. When you arrive at the installation folder path setup dialog, **it’s vitally important to make sure you install to c:\adt2005 (not Program Files (x86)\AutoCAD Architectural Desktop 2005 as prompted by default)**.

5. Once installed, make sure you fully close the AutoCAD Architectural Desktop setup program (because the Converter is waiting for the setup program to close) then
   1. Go back to the Converter tool
   2. Select the 3rd tab named “Old AutoCAD Program Reviver”
   3. Pick the newly installed c:\adt2005 folder and click the “Fix” button at the bottom.
6. Next, run your AutoCAD Architectural Desktop 2005
   1. NOTE: If you see a warning dialog when you run saying “This program has known compatibility issues”, simply click “Don’t show this message again” and then click “Run the Program without getting help”
7. You can now run your AutoCAD Architectural Desktop 2005 on Windows 7, Windows 8, Windows 8.1 and Windows 10 but first we recommend you install the following Service Packs…
