Possible Path environment variable corruption by EmEditor v15.1.1

If you have installed EmEditor v15.1.1 as the entire machine install (Selecting “Everybody (all users)” in the Installation Type during the install), and if the system “Path” environment variable is 1,000 characters long or longer, the system “Path” variable might have become corrupted (or erased) during the install.

The problem could happen only if you use the v15.1.1 installer, and NOT by any other versions of installers. The problem could happen only if your Path environment is longer than 1,000 character long.

To check your “Path” variable, please go to Control Panel, System Properties, Advanced system settings, click the Environment Variables button, and scroll down the System variables list box to find the “Path” variable.  The “Path” variable should contain several application paths combined with semicolons (;).  In the Registry, the “Path” variable is stored at:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

If this variable contains only the EmEditor path (C:\Program Files\EmEditor), the “Path” variable has been corrupted, and the installer erased the previous “Path” variable.

If this happens to your system, your original Path variable can be found at one of the following keys:

HKEY_LOCAL_MACHINE\SYSTEM
   \ControlSet001
   \ControlSet002
   \Clone

If you find a good “Path” variable, you can copy and paste to the current “Path” variable.

If you still can’t find the old good original path, the following article might be able to help you.

The new installer of EmEditor (v15.1.2) has fixed the bug, but once you install v15.1.1, installing v15.1.2 alone will not help you fix the Path variable.
We sincerely apologize for any inconveniences if this has affected your system.

Thank you for using EmEditor!
