If your installed AutoCAD is hanging on startup then read this post first AutoCAD Freezes on startup (AutoCAD visible but the menus don’t appear)
Your 64bit AutoCAD 2010 was never designed to run in Windows 10, Windows 8 or Windows 8.1 64bit (these versions of Windows are newer than AutoCAD 2010) – you may see random crashing, hanging on startup and/or slow performance…
NOTE: If you are running VBA macros in AutoCAD and they are running extremely slowly, you can gain up to 1000x better performance by installing the 32bit version of AutoCAD 2010 on 64bit Windows
In order for your AutoCAD 2010 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.
- Obtain your purchased copy of the Longbow Converter here
- Install your 64bit AutoCAD 2010 as normal.
- Once the installation process is complete, close the setup program then start our Longbow Converter software
- Select the 3rd tab named “Old AutoCAD Program Reviver“
- Pick the “…” button to select newly installed C:\Program Files\AutoCAD 2010 folder
- then click “Fix Old Program”
- Now you can happily run your AutoCAD 2010 64bit on Windows 10, Windows 8 and Windows 8.1 64bit.
– if your AutoCAD hangs on startup (stuck at the “Checking License…” message, try installing the 32bit version of AutoCAD 2010 on 64bit Windows – we’ve actually found the 32bit AutoCAD 2010 running on 64bit Windows is much more stable and actually faster than the 64bit version of AutoCAD 2010.
– If you are unable to activate your product, or the activation process crashes:
- Try uninstalling the July 2014 Microsoft security update
- Try downgrading your Internet Explorer (IE) from version 11 to version 10 by following the instructions detailed here
– If you have crashing problems using the File->Open or File->Save dialogs inside of AutoCAD please read this blog entry on the File->Open or File->Save Crash in AutoCAD
