If you are having trouble installing, uninstalling or updating EmEditor, please refer to the following tips. We apologize for any inconveniences.

1. If you use Trend Micro, Avast, or any other Antivirus or Security software, temporarily disable the software and install EmEditor.
2. Close all currently running programs including icons in the Taskbar notification area.
3. Check if the Windows system is up to date by Update Windows, and then restart Windows.
4. Use the Disk Cleanup to clean system files. To start Disk Cleanup, search for Disk Cleanup from the Start menu, click the Clean up system files, and clean all files.
5. Delete all files in the %TEMP% folder, and restart Windows.
6. If the error message that says “The feature you are trying to use is on a network resource that is unavailable.” appears while trying to update or install EmEditor, first locate the installer of the previous version. The installer of the previous version can be found in one of the C:\ProgramData\Emurasoft\EmEditor\updates\update… folders. Some old versions can be downloaded at http://files.emeditor.com/emed64_xx.x.x.exe (64-bit) or http://files.emeditor.com/emed32_xx.x.x.exe (32-bit) where “x” represents a version number. For instance, in case of v15.6.1 (64-bit), it becomes http://files.emeditor.com/emed64_15.6.1.exe. Extract the installer with the “/extract” option in Command Prompt. For example, if the installer is “emed64_15.6.1.exe”, you would run: “emed64_15.6.1.exe /extract”. This will create a sub folder with file contents. Inside the folder, you will find a file with the file extension “.msi”, in this case “emed64_15.6.1.msi“. Click the Browse button in the above dialog box, and specify the .msi file.
7. If unable to update, first uninstall the old version from Control Panel, and restart Windows. Make sure the old EmEditor install folder is empty (usually C:\Program Files\EmEditor or %LOCALAPPDATA%\Programs\EmEditor), and then install a new version.
8. Use Microsoft Fix it tool to check the system for Windows Installer.
9. Check the hard disk by Chkdsk command in the Command Prompt run as administrator. This process might take several hours.
10. Check the system by sfc /SCANNOW command in the Command Prompt run as administrator. This process might take several hours.
11. The Windows System Restore might be able to restore your computer settings to an earlier date.
12. If there are permission issues while trying to uninstall EmEditor, try creating a new administrative account, and uninstall with the new account.
13. GeekUninstaller (freeware) or Revo Uninstaller (freeware) might be able to help you uninstall an old version.
14. If the Check for Updates fails, select Customize Update Checker on the Help menu, and make sure the Download Folder specifies a writable folder. The default is C:\ProgramData\Emurasoft\EmEditor\updates.
    If it still fails, please download the newest version, and run the downloaded installer.
15. When updating EmEditor, if a system restart is required, close all applications before updating EmEditor. In particular, Brother Control Center (BrCtrlCntr.exe), which comes with Brother printers, might open the EmEditor folder, and thus please close the Control Center you might find in the Taskbar Notification Area. If the problem persists, use Process Explorer and search for any open handles to the EmEditor install folder when a system restart is prompted.
16. To report issues during the install, run the installer with the “/L*V log.txt” option. For instance, if the installer is emed64_21.0.0.msi, run “msiexec /i emed64_21.0.0.msi /L*V log.txt”. If installing to the whole computer, the Command Prompt is required to run as Administrator. To report issues during the uninstall, run the installer corresponding to the version you want to uninstall with the “/L*V log.txt” option. Zip the log file “log.txt”, and email to our support at tech at emurasoft.com with detail information.
17. If EmEditor complains that “eeupdate.exe” is missing during EmEditor install or launching EmEditor, Antivirus software seemed to delete the eeupdate.exe file while EmEditor was installed or launched. Please consider disabling the antivirus while installing EmEditor, or add the file to exception list of the antivirus. If this doesn’t work, you can install EmEditor without copying eeupdate.exe. To do this, when you install, select “Custom” install, in the Custom Setup screen, expand the “Program Shortcuts and Association” and disable “Check Updates”. Alternatively, you can create the “CheckUpdates” value as REG_DWORD in the HKEY_LOCAL_MACHINE\SOFTWARE\EmSoft\EmEditor v3\Common key, and assign 0. Either of the above methods will completely disable the update checker and the eeupdate.exe will not be searched anymore.
18. If the “Called RunScript when not marked in progress.” message appears, please check the permissions include writable on C:\Windows\Temp folder.
19. If you run EmEditor on a PC where the Internet connection is unavailable, you might run into an issue such as:
    – A warning dialog box “The digital signature of a program file could not be verified.” appears when you try to launch EmEditor.
    – The digital signature of EmEditor files (such as emeditor.exe and .msi installers) cannot be verified.
    – EmEditor launch becomes slow.

    In these cases, please see EmEditor Help: The digital signature of a program files could not be verified (when the Internet connection is unavailable).

20. Starting with EmEditor v24.2, EmEditor is installed as a per-user install only, and EmEditor does not support a per-computer install anymore. We recommend using the per-user install because it will be safer and easier to update in the future. If you need to change the install folder, please see How do I change the install folder.
21. If you are unable to install the new version because of the following message despite having uninstalled the previous version of EmEditor:
    “The old version was installed for all users (per computer), but the new version does not support per-computer installations. Please remove the old version from Windows Settings, and install the new version.”

    Please open the Registry Editor (`regedit.exe`) and search for the following key:

    HKEY_LOCAL_MACHINE\SOFTWARE\EmSoft\EmEditor v3

    If this key remains, please delete it.
