ThinkPad Bluetooth with Enhanced Data Rate Software Problem

I'm having a weird issue. I use a X200t tablet with Windows 7 Profession 64-bit.


Apparently my current "ThinkPad Bluetooth with Enhanced Data Rate Software" is Version.


Thinkvantage System Update wants me to download and install Version


However, it tries and I get Error 1935 and it rolls back. Now when I start windows I get an alert about BTTray.exe not loading.


Of course I searched this problem, but it seems to be some ancient thing (years old) and I've never had a problem before with any of the Bluetooth updates.


I did notice that in past versions people said when they tried to uninstall the old version and install the new one, it just wiped their hard drive. I don't want to risk that so I thought I'd check here if anyone knew what was going on.

Re: ThinkPad Bluetooth with Enhanced Data Rate Software Problem

I have had this problem with a Yoga 3 pro (1370) for quite some time and it happens only on Chrome and only on certain websites.


Reviewing the supported models and Windows versions, this update does apply and I can not find one for this Yoga or Win 10.


The originator of this thread was cautious of a malfunction after installing this update and I share that sentiment, esp since the instructions do not include my unit or OS. Has anyone found the bluetooth driver for a wider range of model numbers? I have no desire to address a disaster over the annoyance of the OEM driver crashing Chrome.
