Known Issues and Current Status

/in /by

This page contains important information regarding the current version issues and their status. The information is being updated frequently.

Some issues might be already fixed in recent versions including preview versions. Please try updating EmEditor to the latest version including preview versions if you believe there are any issues.

Version 24.5.0

  • When trying to uninstall using the desktop version installer, you might encounter a “Custom Action Parameter Error” that stops the uninstallation process. This problem has been fixed in the latest version. To resolve it, go to Help and click on Check for Updates to update to the newest version. Alternatively, you can download the latest version here and run the installer. Once updated, you can proceed with the uninstallation.

From Version 22.4.0 through Version 24.4.1

  • When opening large files (approximately 300MB or more) from a slow hard drive, EmEditor may load duplicate lines, especially if the initial loading is fast and then slows down. If you edit and save the file without noticing this, some text in the file may be saved as duplicates, potentially increasing the file size. This issue was addressed on the latest version.

Version 23.0.3

  • EmEditor may crash as STATUS_ILLEGAL_INSTRUCTION if running on an old CPU not supporting SSE4.2 (for instance, Intel Core 2 Duo released in 2006). The crash was due to a bug in Visual Studio v17.8. The issue was addressed on the latest version.

Version 23.0.2

  • EmEditor may not be able to save workspaces, wrap lines, or show outlining if Keep Locked is selected from the Changed by Another Program drop-down list in the File page of configuration properties. This issue was fixed on the latest version.

Version 23.0.1

  • Macros might stop working by default. To work around this issue, clear the Run macros asynchronously by default option, or set the Use V8 as JavaScript engine option in the Customize Macros dialog. This issue was fixed on the latest version.

All Versions

  • Starting with v23.0.0, the local Help format was transitioned from a single CHM file to multiple HTML files, and the Help will be displayed in a web browser. The Help pages are local if the URL is a local path.
  • If EmEditor crashes when you deal with a very large file, incrasing the virtual memory might prevent the crash. Please see How to Increase Virtual Memory. You could also avoid this problem by reducing the Number of Threads in the Advanced page of the Customize dialog. On v23.0 or later, you could also avoid this problem by setting the Use temporary files while editing option in the Advanced page of the Customize dialog, but it will lower the speed.
  • Pressing the Hankaku/Zenkaku key on a Japanese keyboard might cause EmEditor to crash. This is a bug of Windows. If this issue persists, please revert to a previous version of an IME.
