Your 64bit AutoCAD Architecture 2014 (ADT 2014) was never designed to run in Windows 10 (this version of Windows is newer than AutoCAD 2014). In order for your AutoCAD Architecture 2014 to run as it did in previous versions of Windows, you need to follow these easy steps…
NOTE: These steps do not bypass normal Autodesk licensing/authorization, you should expect to use your own serial numbers in the normal way.
Make sure all previous installed versions of AutoCAD 2014 are uninstalled first.
Using Windows Explorer, copy Disk 1 of your AutoCAD Architecture 2014 CD to your hard drive, to a folder path c:\Autodesk\ADT2014
If you have more CD’s, copy them all directly over the top of Disk 1, overwrite all files in your previously copied c:\Autodesk\ADT2014 folder
If you have a single self extracting exe downloaded from Autodesk called something like AutoCAD_Arch_2014_English_Win_32_64bit_en-us_Setup.exe
Simply run the exe, it will ask to unzip to a folder inside of c:\Autodesk, make a note of the folder for later use (we’ll refer to it from here as c:\Autodesk\ADT2014), now click OK. Wait until all of the files have extracted, when they do, the AutoCAD Architecture 2014 setup will automatically launch – simply close it and move to the next step.
Now, start the Longbow Converter tool, select the 1st tab, pick the c:\Autodesk\ADT2014 folder, and click the Convert button.
Once the conversion process is complete, click Install/Run Setup to start setup. Simply install as normal.
