User is prompted with “PaperVision Web Assistant Not Found” message when using Firefox

Description


When using the Firefox browser with PaperVision Web Assistant, the user is prompted that the PaperVision Web Assistant was not found, even though the user has in fact installed this component.

Summary


There are three scenarios that cause this behavior.

  1. Scenario 1: A Firefox user installs the PaperVision Web Assistant through the Firefox browser (i.e. Firefox is open during the installation). When a user then tries to view a document using the Web Assistant in Firefox they get a PaperVision Web Assistant Not Found message.
    1. To resolve this issue, close and then re-open their Firefox browser.
    2. Firefox should now detect the PaperVision Web Assistant.
  2. Scenario 2: If a user installs the PaperVision Web Assistant and then installs Firefox, when they attempt to view a document within Firefox (via the Web Assistant), they get a PaperVision Web Assistant Not Found message. This only happens when Firefox is installed after the Web Assistant has already been installed.  To resolve this issue, user can either:
    1. Un-install the Web Assistant, and then re-install the Web Assistant.
    2. The user can browse to C:\Program Files (x86)\Digitech Systems\PaperVision\PVWA and execute “FirefoxUtil.bat”. This batch file will automatically add an exception to Firefox for the Web Assistant’s SSL certificate.
  3. Scenario 3: If Windows user other than the account that installed Firefox, who does not have administrator rights on the machine attempts to view a document, they are prompted that the PaperVision Web Assistant is not installed. To resolve this situation, the user needs to add a security exception in Firefox:
    1. Open Firefox.
    2. Browse to https://localhost:8731/dsi.pvwa.host/iservicelistener/help (where ‘8731’ is the port selected for the PaperVision Web Assistant)
    3. Click on the option “I Understand the Risks”
    4. In the window that opens up, enable the option “Permanently store this exception” and then click “Confirm Security Exception”.

Note: Firefox’s option to “Always use private browsing mode” must be disabled in order to make the change in Scenario 3.
