Description:
Symptoms:

- If the default installation directory was used, the start.htm file will be located at: C:\Program Files (x86)\TIBCO\TIBCO iProcess Server Objects (Java)\Help. When we click on it using any modern browser like Google Chrome or Microsoft Edge, the screen flickers, and nothing happens.

- If we try the same on Internet Explorer, it works.

Cause:
The issue happens because the start.htm file is loaded using the file:// protocol.
Modern browsers treat this as a different origin, which causes cross-origin security restrictions and blocks access between frames.

TIBCO iProcess Server Objects (.NET)

OS: Windows

Note: Enabling file access from URLs can pose security risks. It's generally recommended to use these settings only when necessary.

To fix this, we can set Microsoft Edge to open the start.htm file in Internet Explorer (IE) Mode.
By adding the local file path to the IE Mode list, Edge will open the file using older compatibility settings and avoid the security restrictions.

Steps to configure Microsoft Edge to open start.htm in IE Mode:
1) Open Microsoft Edge.
2) In the address bar, type edge://settings/defaultBrowser and press Enter.
3) Find the option “Allow sites to be reloaded in Internet Explorer mode” and change it to Allow.
4) Under “Internet Explorer mode pages,” click Add.
5) Enter the full file path for the start.htm file. (You can open the file once, copy the path from the address bar, and paste it here.)
6) Close and reopen the file; it should now open automatically in IE Mode without errors

Steps to configure Google Chrome to open start.htm:
1) Right-click on your desktop → New → Shortcut.
2)In the location field, type:
"C:\Program Files\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files
(If your Chrome is installed elsewhere, adjust the path accordingly)
3)Click Next, give it a name like Chrome with File Access, and click Finish.
4)Now, use this shortcut to open Chrome, and then open your start.htm file by either:
5)Typing file:///C:/Program Files (x86)/TIBCO/TIBCO iProcess Server Objects (Java)/Help/start.htm in the address bar, or dragging and dropping the start.htm file into this Chrome window.

Steps to configure Firefox browser to open start.htm:
1)Open Firefox. In the address bar, type:
about:config
and press Enter.
If a warning message appears (“Proceed with Caution”), click “Accept the Risk and Continue”.
2)In the search bar at the top of the config page, type:
security.fileuri.strict_origin_policy
The setting should appear in the list.
Its default value is true.
3)Double-click on it (or use the toggle button) to change its value to false.
Close the tab — the setting takes effect immediately.
4)Now, open the start.htm file in Firefox by:
Typing file:///C:/Program Files (x86)/TIBCO/TIBCO iProcess Server Objects (Java)/Help/start.htm in the address bar, or dragging and dropping the file into the Firefox window.
