Windows Certificate Store and CA chain validation

Hi,
Could you please help me to setup ICE configs to use the Windows Certificate Store for CA chain validation?

The server-side [Win10 / ICE 3.7.2] has a root CA certificate on "Local Computer\Truted Root Certification Authorities\Certificates", and an application certificate imported on "Local Computer\Personal\Certificates".
The ICE configs, related to the CA validation, are defined as:
IceSSL.VerifyPeer=0
IceSSL.FindCert=thumbprint:thumbprint_of_app_stored_certificate
IceSSL.CertStore=My
IceSSL.CertStoreLocation=LocalMachine

The client-side [Win10 / ICE 3.7.2] has the same root CA certificate on "Local Computer\Truted Root Certification Authorities\Certificates".
ICE configurations, related to the CA validation, are defined as:
IceSSL.VerifyPeer=1
IceSSL.UsePlatformCAs=1

But, when I try to establish the connection, I got the following errors (provided by Ice.Trace):

Security certificate verification failure
issuer = /O=content/CN=content
subject = /O=content/CN=content
depth = 0
error = unable to get local issuer certificate
local address = 192.168.162.1content
remote address = 192.168.162.132:content

Security certificate verification failure
issuer = /O=content/CN=content
subject = /O=content/CN=content
depth = 0
error = unable to verify the first certificate
local address = 192.168.162.1:content
remote address = 192.168.162.132:content

Network IceSSL: certificate verification failed:
unable to verify the first certificate

However, If I configure client-side to use "IceSSL.CAs=C:\testcerts\rootCA.cer" directly, instead of the Win Cert Store (IceSSL.UsePlatformCAs=1), it works as expected.

Besides that, I did the same test using a simple client-server C++ code (instead of our client-server C++ solution), only with the CA-related ICE properties defined, and the connection works (same systems and same certificates). Based on that, I'm suspecting of an ICE property conflict at this point.
