Fix "Ac1st16 DLL" AutoCAD Errors – Working Tutorial To Repair Ac1st16 DLL Errors On Your System

ac1st16.dll is a file used by the “AutoCAD” program to help load up a number of extremely important features for programs developed by “AutoDesk, inc” – the producers of AutoCAD. This file is used by all versions of AutoCAD to load up a number of important settings that are required to help run the advanced data & user interface elements of the program. More specifically, the ac1st16 file is used to control the “ObjectDBX” element of the tool (used to control the huge amount of data which AutoCAD uses each day). If you’re seeing ac1st16.dll errors on your PC, you need to resolve them as quickly and effectively as possible – which can be done by using the steps outlined in this tutorial.

The errors which this file causes includes the likes of:

  • “ac1st16 Not Found”
  • This application failed to start because ac1st16 was not found. “
  • “Cannot start Autodesk ObjectDBX. A required component is missing: ac1st16.”

The errors which are shown with this file are generally caused by 2 possible problems on your computer. The first is that somehow, AutoCAD has become damaged or corrupted, preventing your computer from being able to run it correctly. To ensure this problem is not a big issue for your PC, you should look to re-install AutoCAD (or any other program which may be causing the ac1st16 error). This can be done by first clicking onto Start > Control Panel > Add / Remove Programs and then locating the AutoCAD program that your computer has. This will then allow you to get rid of the program, which should resolve the potential problems which may be causing the errors to show. After that, reinstall the program you just removed and then replace the ac1st16 file if the error still appears.

After you’ve re-installed the software showing the error, you should then use what’s known as a “registry cleaner” program to fix any potential errors that may be inside the registry database of your PC. This is a central storage facility for all the settings and options which Windows uses to run, and is a highly important part of every Windows system. Unfortunately, the registry is continually causing a huge number of problems because many of its important files are continually being damaged and corrupted – leading to many strange errors. The error will likely be caused by a registry issue if re-installing the program did not fix it. This means that if you still see the error, it’s recommended you download a reliable registry cleaner to resolve the possible problems that Windows may have inside its registry database. This should fix the problem for good.
