BTOE 3.4.0 - Cannot verify digital signature

Hello,

 

When attempting to install the BTOE 3.4.0 connector, some machines are spitting out an error for the BTOE Enumerator stating: 

"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"

 

This error disables the use of the connector and can only be installed if I DISABLE secure boot mode.  I've tried to manually add the cert located here  but I am having the same issue.  Againt, this only happens to a selected number of test machines.  Others installed fine without an issue.

 

The end goal is to run a silent install script so we can deploy to all end-users.  However, this digital signature seems to be getting in the way, even when attempting to install by directly running the MSI.

 

Any help is greatly appreciated.

Have the same issue as described above. Is BToE 3.4.0 supported on Windows 10 1607? Haven't found that information anywhere.

Hello jedge,

welcome to the Polycom Community.

Since BToE 3.3.0 we do support Windows 10 as stated in the release notes.

 

Please gather the logs in Debug mode and then open a ticket. If you are having trouble please post a MAC address of a Phone affected.

Re: BTOE 3.4.0 - Cannot verify digital signature

I have the same issue!  Turns out 3.4.0 works just fine with W10 1511.  However with W10 1607 there is an error during install (Windows blocked the installation of a digitally unsigned driver), and it continues to ask you to 'Please Restart your PC to complete the installation' over and over until you uninstall BTOE 3.4.0.  

 

I will certainly raise this issue to my reseller, however this is a very repeatable issue, in addition to a significant one.  As of right now I am unable to deploy any polycom phone to any of my current W10 clients and that is a huge gap for my deployment at the moment.

 

Dev need to get 3.4.1 released with a fix immediately!

 

Thanks!

Re: BTOE 3.4.0 - Cannot verify digital signature

Hello STRiCT,

welcome back to the Polycom Community.

I have just installed BToE 3.4.0 on a Windows 10 machine running the 1607 build and I did not get this message and BToE works fine.

 

Unless this is escalated into our support organisation by one or multiple of you three users responding to this post we are unable to check or correct this. 

 

So far I have not yet seen any tickets on this.

 

I have seen Jake's post => here <= but he has not provided any details like a Polycom SR or any other details.

 

 

We are unable to comment on any unreleased software versions or any timeline without dealing directly with a user or their reseller.

I also thought it might be windows 10 v1607 but I tried it on two test machines, both with the same versions.  One installed fine, the other failed.  I am really hoping for an update.  Despite this issue, the BTOE feature is amazing

Interesting!  All our W10 1607's are on build 14393.576 which are not working with 3.4.0.  Our W10 1511's are on build 10586.713 which are working with 3.4.0.  The only other potential difference I can think of is we are exclusivly using W10 Enterprise in a Active Directory domain enviroment co-managed by Intune.

UPDATE:  I've been in contact with Polycom and Microsoft via email.  They stated that the cert expired and they are working on getting it renewed.  We should be expecting version 3.4.1 hopefully this week.  I will continue to monitor this and report back if a new version drops.
