Opening a host session file results in message “Could not read file…”

• A Reflection  settings file has been moved from a Windows 7 Desktop folder to Windows 10 Desktop folder. 
• Opening this file by double-clicking on it results in the message "Could not read file C:\Users\<username>\Desktop\<sessionfilename>. 
• The error is a Reflection Workspace pop-up message with an OK button. 
• After clicking OK the user is left with the Workspace but no session. 
• Adding the desktop folder to "Trusted Locations", or disabling the "Trusted Locations" security feature altogether has not resolved the issue.
  

1. Launch the Reflection Workspace.
2. Go to the File menu and select Reflection Workspace Settings.
3. Under Workspace Settings, click the Configure Workspace Attributes.
4. Scroll Down to the Directories section.  Change the "Default user data directory:" value to a path that actually exists. 

Note: The Default user data directory path is the location that Reflection will open to when using File-Open, File-Save, or File-Save As.   This is usually C:\Users\[username]\Documents\Micro Focus\Reflection.

The "Default user data directory" setting is saved in the "application.settings" file for each Reflection user, which is found in C:\Users\[username]\AppData\Roaming\Micro Focus\Reflection\Desktop\[version]\. In this case, the application.settings file deployed to the Windows 10 computer came from another computer on which workspace settings had been configured.  This resulted in a saved default user data directory value that did not exist.  To avoid this problem, application.settings files that will be deployed to other machines must be defined using the Micro Focus Installation Customization Tool, not copied from another computer.  See the Reflection Deployment Guide for more information -
