I am trying to install the Broadcom Bluetooth stack via their software install program SetupBtwDownloadSE.exe. My BT dongle is a Rocketfish RF-mrbtad installed in a USB port. Operating system Win 7 64 bit SP1. The installation application crashes at the "verify bluetooth" stage of installation and the expanded error code is as follows: Problem Event Name: APPCRASH Application Name: BtwDownload.exe Application Version: 126.96.36.199 Application Timestamp: 4a275189 Fault Module Name: BtwDownload.exe Fault Module Version: 188.8.131.52 Fault Module Timestamp: 4a275189 Exception Code: c0000005 Exception Offset: 000000000002776f OS Version: 6.1.7601.2.1.0.768.3 Locale ID: 1033 Additional Information 1: 1080 Additional Information 2: 1080124fb2d47a7035ffa7ecae86530c Additional Information 3: 72b0 Additional Information 4: 72b07af89d3d0ff5d81bbe49d5e082f2 Does anybody have a workaround for this? The standard MS drivers do not support all the services I need for my mobile phone, and I know the Widcom drivers do. Thanks.
