When signing in to activate Version 10, you may see the error “Microsoft Edge can’t read and write to its data directory” and the sign-in window appears blank.


This occurs when the expected WebView2 data folder is missing.

How to Fix the Issue

  1. Open the folder shown in the error message
    In most cases, the path will be: C:\Users\[username]\AppData\Local\Temp\TTSDesktopAuthentication
     

  2. Create the required sub-folder
    Inside this folder, create a new folder named: EBWebView

  3. Restart Version 10

    • Close Version 10 completely.

    • Re-open it.

    • Select Sign in to Activate again.
      Once the EBWebView folder exists, the authentication screen should load correctly.

  4. If the issue still persists, navigate to the location where V10 is installed, which is most likely C:\Program Files (x86)\Timetabling Solutions\Timetabling Solutions Version 10. Right-click ActivateSoftware.exe and select 'Run as Administrator'.

    If the issue persists, please contact support@timetbling.com.au
