ENA v18.0 known issues

Windows bug affecting patch installs (ENA v17.0/v18.0 and Entuity v19.0 on Windows Server 2016/2019)

Windows bug affecting patch installs (ENA v17.0/v18.0 and Entuity v19.0 on Windows Server 2016/2019):

There is a bug in Windows, as of December 2018, affecting any version of Entuity that is using Windows Server 2016 or Windows Server 2019, that can remove a temp directory that installPatch requires to run.

In Windows, user sessions are given their own temporary storage location, which is stored in the temp or tmp environment variables. This location is: C:\Users\Username\AppData\Local\Temp\session_id.

The bug, however, can remove the folder under temp for that session. The symptom of this issue is the following error:

"ERROR: Unable to install patch. The system cannot find the path specified."

This occurs even though the patch file supplied does exist.

The solution is to update the environment variable. There are two ways to do this:

• find the temp directory by running echo %TEMP% in cmd, and then create the folder manually.

or

• set a custom temp directory using the following commands in cmdset:
  

  set TEMP=\temp
  set tmp=\temp
