Downloading the asctrls.ocx file

We don't advise to download the asctrls.ocx file and copy it to the Windows system directory. The software's creators almost never circulate the DLL files, they are always part of an installation set. It's the installation set's task to perform the sufficient verifications before the installation. An incorrectly installed DLL file may cause the system's complete inability to function.

If you need a DLL file in spite of the above for the sake of restoring a system, then download it from a reliable source, possibly from the manufacturer's site.

Use the System File Checker tool

To solve the asctrls.ocx file's problems, check if the system files are intact as a first step.

System File Checker (SFC.exe) is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. If a Windows Resource Protection (WRP) file is missing or is corrupted, Windows may not behave as expected. For example, some Windows functions may not work, or Windows may crash.

To scan all system files, open a command prompt as an administrator and type:

sfc /scannow

This command will scan all protected system files, and replace corrupted files with a cached copy that is located in a compressed folder at System32\dllcache.
