As described on the download page, TetherBridge is digitally signed with the newer Microsoft Authenticode, introduced after the release of Windows XP. Windows XP does not recognize Microsoft Authenticode for driver signing. Windows XP will by default warn users with a message about "...not passed Windows Logo testing..." but gives an option to install anyway. The user needs to hit "Continue anyway" option (two such instances for two components) to get the software installed. However, on some XP machines, the user may not be given this option but instead get the following message "This software will not be installed. Contact your system administrator." after the Windows logo testing warning.
This issue is caused by a misconfiguration of the XP machine and can be corrected by a simple configuration change. XP has selectable options for dealing with such deemed violations, in particular, the Warn and Block options. The default is "Warn" where the user is warned about the potential problem but is given an option to continue with the installation. When the system is configured with "Block", no option to continue with installation is given to the user. To change the system to the default "Warn" behavior, go to Control Panel->System->Hardware->Driver Signing and set it to "Warn".
When the installation proceeds normally, during the process of the installation the user will be presented with an option in a pop-up window to authorize the installation of the TetherBridge network adapter. This pop-up window from the Windows OS will also identify the publisher as TetherBridge. This pop-up window will appear only after Windows OS has verified the signature of the driver component of the TetherBridge installer file. An installation can fail before this window has ever appeared for multiple reasons:
The first possibility is that the installer file is corrupted during downloading. One particular user actually ran into this problem with two of his PCs when attempting installation from home repeated. He was able to install it on his laptop after taking the laptop to his office. The problem might have been associated with corruption on his home router.
The second possibility is that Windows OS is not properly configured with the right admin rights for installing a kernel driver. Vista and W7 has a UAC mechanism controlling who can install what type of software. Installation of software containing a kernel driver (TetherBridge being one) requires additional permission compared to installation of a regular software program. First of all, TetherBridge can be installed only from an account with admin rights. Configuration options exist which can even lock some admin accounts out from installing software with kernel drivers. You are referred to the following link for more info on UAC: http://technet.microsoft.com/en-us/library/cc709691(WS.10).aspx
The general installation instructions are targeted to those users who use TetherBridge mainly while traveling. It is assumed that the user has Internet connection when installing the software to his/her PC. If the PC does not have Internet access to start with, there are still a couple of ways to install the software. Note that we require the Blackberry Desktop Manager/Software be installed as well. Because the Blackberry Desktop Manager/Software installer file is quite large and a Blackberry device does not allow it to be downloaded and saved on the BB, the alternative of using your Blackberry to download will not work out if you need to download the Blackberry Desktop Manager/Software installer file as well.
