What are acad.pat Error Messages?


General acad.pat Runtime Errors

acad.pat file errors often occur during the startup phase of AutoCAD, but can also occur while the program is running. These types PAT errors are also known as “runtime errors” because they occur while AutoCAD is running. Here are some of the most common acad.pat runtime errors:

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\Autodesk\WI\Autodesk AutoCAD 2020\x64\en-US\acad\AcadPS\PF\Root\UserDataCache\Support\acad.pat

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.


Most PAT errors are due to missing or corrupt files. Your acad.pat file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with AutoCAD), or deleted by a malware infection. Furthermore, acad.pat file corruption could be caused from a power outage when loading AutoCAD, system crash while loading or saving acad.pat, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve acad.pat problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.



Download acad.pat Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying acad.pat to your appropriate Windows system directory. Autodesk, Inc. typically does not release AutoCAD PAT files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing acad.pat and all other PAT files for AutoCAD. An incorrectly installed PAT file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
