After installing, why did Internet Explorer report a
HTTP 500 Internal Server,
or web page cannot be displayed
This error can occur if the Internet Explorer browser settings interfere
with local web serving. Using the IE menu, select
Tools >> Internet Options >> Connections Tab >> LAN Settings
and ensure that Automatically detect settings and
Use automatic configuration script checkboxes
are both not checked.
As an alternative, enter your PC's IP address in the browser
address bar (e.g., http://192.168.0.1).
If you don't know your IP address, start a command prompt window
(e.g., Start >> Run >> cmd) and type ipconfig
to view your IP address.
After installing, why didn't the main menu appear?
BadBlue's user interface runs in a browser. If a browser window does not
pop up automatically, right click on the BadBlue icon in the
system tray (lower righthand corner of the screen) and select
Main menu. Or click on this link -
http://127.0.0.1/index.htm - to see whether BadBlue is running.
This can occur the first
time you run BadBlue if you use a software firewall (e.g., ZoneAlarm).
Tell ZoneAlarm that BadBlue (P2P web server) is permitted to both
act as a server and access the internet. You can also try
simply refreshing the browser window and the main menu should appear.
The browser says 'Page cannot be displayed' or 'Cannot find server', what do I do?
Press the browser Refresh button.
For instance, if you're running ZoneAlarm,
it will ask whether BadBlue can access the Internet and act as a server?
On both questions, check the
'Remember this answer the next time I use this program'
box and press the 'Yes' button.
You can then press the browser's Refresh button
to display BadBlue's main menu. Or right-click on the BadBlue
system tray icon at lower right and select 'Main menu'.
Why do I get "Access Denied (page can not be accessed from a remote browser)"
errors when using the menus?
Usually this is due to one of two reasons:
1) Using a domain-name rather than http://127.0.0.1 to manage BadBlue.
To ensure that the management functions are executed on the local browser, BadBlue needs to
verify the source of the request. When a domain-name is used in the browser address bar (rather
than http://127.0.0.1), BadBlue is unable to confirm the request as
local. Use http://127.0.0.1 in the browser address bar to
manage the local copy of BadBlue.
2) Running security software on your PC.
When running certain firewall or privacy software packages, BadBlue
is unable to verify that the local browser is truly running on your
workstation. The good news is that the most popular programs (e.g.,
Windows XP's built-in firewall, Norton Internet Security and ZoneAlarm)
can be configured to permit
BadBlue to verify its security:

Can BadBlue be installed as a Service?
Yes. A service runs continuously, even when a user is not logged in.
BadBlue can be installed as a Windows 9X service
(Windows 95, 98, ME). From a command-line, use the syntax:
This creates a BadBlue registry setting in:
BadBlue can also be installed as a Windows NT or 2000 service.
From a command-line, use the syntax:
After installing as an NT service, BadBlue can be controlled from
the Start >> Settings >> Control Panel >> Services application.
To remove the service (and transform the executable back into a normal,
non-service executable), use:
To programmatically stop BadBlue, use:
How do I install PHP?
Visit our PHP help page.
Can I install new MIME Types?
Yes. Visit our General web serving.
After installing, why doesn't Netscape display anything?
After installation of BadBlue on a system that uses a proxy server, Netscape
refuses to display the BadBlue user interface. This is caused by Netscape not
understanding that 127.0.0.1 is the local machine and does not need to use the
proxy server. To repair this problem, add 127.0.0.1 to the Netscape proxy
exception list. In Netscape 4.X use the following steps:
Edit >> Preferences >> Advanced >> Proxies >> Manual Proxy Configuration >> View
and add 127.0.0.1 to the "do not use proxy servers for domains beginning with" list.
How do I uninstall BadBlue?
Use Windows Explorer to open the folder to which you originally
installed BadBlue (usually this is
c:\program files\badblue\pe). Then
run the application called
Two items of interest: BadBlue installs files only to the
specified installation folder; removing the folder altogether
is perfectly safe as an uninstall.
Also, because BadBlue uses a very tiny installer to keep its
size to a minimum it does not add information to the
Control Panel's 'Add and Remove Programs' menu.
After installing, why did I get a "port" error?
BadBlue probably installed correctly, but is unable to serve up its web pages.
You may have a port conflict. Right click on the
BadBlue icon in the system tray (lower righthand corner) and select Restore.
The BadBlue console (a small window) should appear. Use the following
steps to change the port number:
Press the Stop button to stop the server
Change the port from 80 to 81 (or other unused port-number such as 8081)
Press the Exit button to exit
Restart BadBlue from the Start menu or Services panel if installed as a service
After changing the port number, it is highly recommended that you
exit completely and restart from the Start menu (or the Services
control panel if BadBlue has been installed as a Windows NT or 2000 service).
