AutoCAD LT 2014 on Windows 11 – FATAL ERROR: acismobj20.dbx

If you are running AutoCAD LT 2014 on Windows 11 and you receive this error…

FATAL ERROR: (0x7ffb71c40005) C:\Program Files\Autodesk\AutoCAD LT 2014\acismobj20.dbx (acismobj20)

The issue is that you are running 64bit AutoCAD LT 2014 on Windows 11, this is an old version of AutoCAD which is easily affected by Windows Updates pushed by Microsoft. You need to install the 32bit version of AutoCAD LT 2014 instead as it is not as easily affected by the latest Windows components. To solve the problem, you must first uninstall your existing AutoCAD LT 2014 (do not install along side as it will not work) and then follow these instructions to install the 32bit version (which is much more reliable and actually runs faster)
