How do I configure my Tuner proxy?

If your site or Internet Service Provider uses an HTTP proxy, obtain its host name and port number. You can get this information from a network administrator, or from a Web browser that you know can reach the Internet.

Why doesn't the Tuner automatically update itself?

The tuner will automatically ask to be updated once every week. You can skip that update, but you can also update more frequently by selecting "Update Tuner" from the Tuner menu.

How do I set a particular browser as the default browser?

Launch the browser (Netscape Navigator or Microsoft Internet Explorer) that you want to be the default. If it's not the default it will ask you if you want to make it so.

I get a message saying to set my web browser's HTTP proxy host to localhost and set the port to 5283.

If you're using Netscape Navigator, go to Network Preferences and select Proxies. Select 'View' for Manual Proxy Configuration. Then enter 'localhost' as your HTTP Proxy and '5283' as your Port and click OK.

If you're using Internet Explorer, go to View and select Options. Choose the 'Connection' tab and check the 'connect through a proxy server' field. Click 'Settings' and enter 'localhost' as the 'address of proxy to use' and '5283' as your Port.

The size of the Tuner has grown to over 5Mb!

The 1.1 Tuner uses Java's JRE1.1.2 which is much larger than the previous version of Java, JDK1.0.2.

Performance for the 1.1 Tuner doesn't seem much better than for the 1.0 Tuner.

The Tuner in version 1.1 is written in Java. Tests we have performed have shown that the performance is better than for the 1.0 Tuner and becomes increasingly better the more channels you have. The Java code runs faster but there is more overhead associated with JRE 1.1.2. (there are a lot more classes to load). The Tuner's performance is limited by Java though we have used caching and optimized code where possible.

I pressed 'Update' to update my Tuner and got an error like "Unexpected file 6ISJFDPMMARJKx2SQJ1PGG200A".

This problem can occur when updating a 1.1beta1 or 1.1beta2 Tuner. The only solution is to uninstall the Tuner then download the latest beta Tuner from http://www.marimba.com/tunein.

Windows Platforms

How do I uninstall the Tuner?

Go to Start->Settings->Control Panels->Add/Remove Programs and select Castanet Tuner.

What are the requirements for running the Windows Tuner?

How do I prevent the Tuner from starting when I boot my computer?

Right click on your Windows Task Bar, choose "Properties" and view "Start Menu Programs." Then remove "Castanet Tuner" from "Startup."

When I set Connection Type to Modem, it complains that I don't have a dialup server.

If you're not using Microsoft's Dialup Networking you will not see a dialup server. You need to change your type of connection from 'modem' to 'direct' in the tuner. This can be done in the Tuner's configure-options tab. Then, you must connect to your ISP/internet provider and then launch the Tuner.

When I start the Tuner I get a 'internal error: java.lang.UnsatisfiedLinkError: socketCreate' error.

This can be caused by using a TCP/IP stack that doesn't work with the JRE/JDK1.1. The MSTCPIP stack with Win95 has been tested and works well. Other stacks, even though they are 32 bit Win95 stacks, may not work.

I'm getting a "corrupt cache" message during the Tuner update.

If you have installed something into your registry which attempts to make your Win95 short filenames look nicer by removing the "~" from the name when possible, then you will run into problems trying to update your tuner. To fix you must edit your registry and remove the binary value named NameNumericTail. To do this, go to the Start menu and select Run, and type the program name "regedit". Under the top level "My Computer", walk down the tree through the following entries, until you find the entry called "NameNumericTail". If you remove this you should be able to update the tuner.

    HKEY_LOCAL_MACHINE
        System
            CurrentControlSet
                control
                    FileSystem
                        NameNumericTail

Remove the entry called "NameNumericTail", restart your computer, and re-install the Castanet Tuner from the InstallShield files. Updates should work at that point.

Note: Norton Utilities 2.0 gives you the option of changing how the short version of the files are named.

When I start the Tuner I get a 'Connection failed tuner.marimba.com:80' error.

Your Tuner is unable to connect to the internet server 'tuner.marimba.com.' This error can occur if you have a true phone/internet line failure. It can also occur if you're an AOL, Compuserve or Prodigy user and you have selected "modem" versus "direct" connection when configuring the Tuner. Make sure you have chosen "direct"; "modem" is only for Windows 95 and Windows NT if you have Dialup Networking configured. Then, you will need to first connect to your service and then launch the Tuner.

How do I make Internet Explorer 3.0 (IE) use the Tuner as a viewer for channels?

  1. Choose the "Options" item in the View menu in IE.
  2. Go to the "Programs" tab in the dialog.
  3. Click on the "File Types..." button
  4. Click on "New Type.."
  5. Enter ".chn" in the "Associated extension" textfield.
  6. Enter "application/marimba" in the "Content Type (MIME)" textfield.
  7. Click on "New..."
  8. Type "Open" in the Action textfield
  9. Enter the path to the Tuner executable that you installed. Typically this path will be "c:\Marimba\Castanet Tuner\tuner.exe"
  10. Click Ok in the New Action dialog
  11. Click Ok in the Add New File Type dialog
  12. Click Ok in the File Types dialog
  13. Click Ok in the Options dialog

I am getting an error about dll's being in use when installing the Tuner.

Before installing Castanet products, it is necessary to completely close all Castanet programs. Some other program may be using the dll when you're trying to install the Tuner. You should not see any Marimba icons in your toolbar in the bottom right.

Using the 1.1 Tuner my Shockwave channel doesn't work.

Shockwave doesn't currently work with 1.1 JRE/JDK. There are efforts to address this problem and we will update this FAQ with further information when available.

What folders are used with the Mac installation?

Installing the tuner creates three folders:

  1. The Castanet Tuner folder, containing the tuner application, is created at the top of the disk you select for installation. You can move this folder wherever you like.
  2. The System:Preferences: marimba folder folder (note: there's a bullet character preceding "marimba") contains the channels the tuner downloads for you.
  3. The System:Extensions:Marimba Libraries folder contains program files shared by Marimba applications.

When I start the Tuner I get a "Connection failed tuner.marimba.com:80" error.
