Cause: Microsoft Edge Infrastructure Change

Historically, Microsoft hosted Edge WebDriver executables on an Azure Blob Storage backend (msedgewebdriverstorage.blob.core.windows.net). Older versions of Inflectra Rapise had this legacy URL hardcoded in its automatic driver management engine.

Recently, Microsoft sunsetted this legacy infrastructure and migrated all WebDriver downloads to a new first-party domain (msedgedriver.microsoft.com). As part of this migration, public read access to the old Azure storage container was completely blocked, resulting in the download error when older versions of Rapise attempt to query the old URLs.

Resolution / Manual Workaround

If you are using an older version of Rapise that still queries the deprecated Azure URL, you must bypass the automatic download and install the Edge WebDriver manually using the new endpoint.

Follow these steps to manually update your driver:

Step 1: Check your Edge Browser Version

  1. Open Microsoft Edge.

  2. Navigate to edge://settings/help in the address bar.

  3. Note your exact build version (e.g., 146.0.3856.109).

Step 2: Download the Driver Manually

  1. Open a web browser and navigate to the new official Microsoft URL format:
    https://msedgedriver.microsoft.com/<VERSION>/edgedriver_win32.zip
    (Be sure to replace <VERSION> with the exact version number you noted in Step 1).

  2. Alternatively, you can visit the official Microsoft Edge Developer site to download the matching release.

Step 3: Install the Driver in Rapise

  1. Extract the edgedriver_win32.zip archive you just downloaded. You will find a file named msedgedriver.exe.

  2. Open Windows File Explorer and navigate to the default Rapise Selenium drivers folder:
    C:\ProgramData\Inflectra\Rapise\SeleniumDrivers
    (Note: ProgramData is a hidden system folder. You can type or paste the path directly into the File Explorer address bar.)

  3. Copy your newly extracted msedgedriver.exe into this folder.

  4. Important: Rapise saves downloaded driver executables with version information in their names to switch between them automatically. Look at the existing files in your folder and rename the newly pasted executable to follow the Rapise naming convention (for example, msedgedriver_146.0.3856.109.exe).
