Installation & Other Software

Due to the observed unpredictable behavior of antivirus software, it is recommended to disable such software during the installation of the Altium NEXUS Server.

If the computer is also running Microsoft Exchange Server, you might receive an HTTP Error 503 error when you first attempt to log in. The installation of the Exchange Server can change the Internet Information Services (IIS) configuration in a way that conflicts with the Altium NEXUS Server. To resolve this, the following changes must be made to the applicationHost.config file:

<handlers accessPolicy="Read, Script">

<add name="kerbauth" image="C:\Program Files\Microsoft\Exchange Server\V15\Bin\kerbauth.dll" preCondition="bitness64" />
<add name="WSMan" image="C:\Windows\system32\wsmsvc.dll" preCondition="bitness64" />
<add name="exppw" image="C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa\auth\exppw.dll" preCondition="bitness64" />
<add name="cafe_exppw" image="C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\bin\exppw.dll"  preCondition="bitness64" />
