After I try to install the 7zbv19ww.exe Bluetooh update, I got this message and the installation rolled back. Did not install.

Tyed with amdinistrator privilege and it still didn´t work.


Error 1935. An error occured during the installantion of assembly.

Re: Bluetooth installation problem

hey kolotelo,

try uninstalling the current bluetooth driver , let windows install its own generic drivers.

can you connect your bluetooth device with generic drivers?

later on, try reinstalling the 7zbv19ww

Re: Bluetooth installation problem

I had that problem. My computer denied upgrading. And when I uninstalled the old version and then tried, worked like a charm. So my tip is to... Uninstall the old one and install after that. My computer demanded a restart. After that I´m happy. smileyvery-happy:
