Hi

on windows 2008 r2 sp1 when you try to install of Dot net 4.2.6 may fail with the below error message: Installation failed with error code: (0x800B010A), “A certificate chain could not be built to a trusted root authority.”

 

According to the CAPI2 event messages inside the log:

<CryptRetrieveObjectByUrlWire>

<URL scheme=”http”>http://www.microsoft.com/pki/certs/MicRooCerAut2011_2011_03_22.crt </URL>

<Object type=”CONTEXT_OID_CERTIFICATE” constant=”1″/>

<Timeout>PT15S</Timeout>

<Flags value=”286005″ CRYPT_RETRIEVE_MULTIPLE_OBJECTS=”true” CRYPT_WIRE_ONLY_RETRIEVAL=”true” CRYPT_LDAP_SCOPE_BASE_ONLY_RETRIEVAL=”true” CRYPT_OFFLINE_CHECK_RETRIEVAL=”true” CRYPT_AIA_RETRIEVAL=”true” CRYPT_PROXY_CACHE_RETRIEVAL=”true”/>

<AdditionalInfo>

<Action name=”NetworkRetrievalTimeout”>

<Error value=”5B4″>This operation returned because the timeout period expired. </Error>

 

Resolution :

 

use the UI provided by the certmgr.msc MMC snap-in to add certificates to the trusted root store. Right-click the Trusted Root Certification Authorities option to display the All Tasks options. The Import option should be used to display the Certificate Import Wizard, which will help you install the root certificate.
To directly download the Microsoft Certificate Authority 2011 certificate, go to
Microsoft Root Certificate Authority 2011.
