SignTool error: SignerSign() failed." (-2147024885/0x8007000b) when signing msi file

2

We recently purchased an EV Code Signing Certificate. I followed instructions and I can successfully sign our built applications (exe files), our libraries (dll). However, I can't sign our setup packages (MSI files), I always get this error:

SignTool Error: An unexpected internal error has occurred. Error information: "Error: SignerSign() failed." (-2147024885/0x8007000b)

I don't see anything in Event Viewer. I am really stuck here, I don't not understand how same command could work for certain file types and not for msi files.

Thanks in advance for your help!

The following cause was reported on a forum post:

Have just found the cause: my antivirus Trend Micro Worry Free Advanced is the problem.

When I deactivate it, I can sign without any problem and it is much faster to sign.

Now I have to find to which part I have to set an exception in the antivirus.

The strange thing is that I never had any problem to sign with my Authenticode certifcate,

but here with an EV Code Signing certificate my antivirus blocks something...
