Installation & Other Software
Due to the observed unpredictable behavior of antivirus software, it is recommended to disable such software during the installation of Altium Concord Pro.
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 Altium Concord Pro. 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" />

► See information on ports and IP addresses for Altium Design software.
HTTPS Protocol Support
For those that require an additional layer of security for exchanging data with Altium Concord Pro, the Server provides for secure communication over networks using the HTTPS protocol to protect the privacy and integrity of the data.
The configuration and server bindings for Altium Concord Pro can be accessed from the Windows Internet Information Services (IIS) Manager panel - available from the Administration Tools window (Control Panel\System and Security\Administrative Tools). Select the 'Altium Concord Pro' entry in the panel's Connections\Sites list, and choose the Features View tab.

Access configuration and server binding settings for Altium Concord Pro.
The available ports and server names for Altium Concord Pro are shown as selectable links in the Actions pane. Use the links to note and test the server connection protocols, or access the current name/port bindings by selecting the Bindings link in the Edit Site section of the pane.
A Binding, including its protocol port number, can be edited from the Site Bindings dialog via the Edit button.

Configure bindings through the Site Bindings dialog.
Note that the server name localhost only applies to the local machine, so PCs other than the one that is hosting Altium Concord Pro need to use the actual (server) name of that host machine to connect.
To confirm the name of the host PC on which Altium Concord Pro is installed and running, on that machine go to Control Panel\System and Security\System and note both the Computer name and Full computer name (its qualified domain name) - the latter will be that used by Altium Concord Pro for secure connections over the network.

Checking the name of the PC on which Altium Concord Pro is running.
To establish a secure connection to Altium Concord Pro:
-
From Altium Designer - use a HTTPS prefixed server address and the configured HTTPS port. By default, this is
https://localhost:9785when using the PC that hosts Altium Concord Pro, orhttps://<computername>:9785for a remote connection (where[computername]is the host machine's Computer Name or qualified domain name).
-
From a Web Browser - enter the address of the local service (
https://localhost:9785) or the host computer name equivalent (https://<computername>:9785).
When Reconfiguring Site Bindings
If you have added a new IIS Site Binding for the server, or edited an existing Site Binding entry (see above), the server PC should be restarted to correctly establish the new configuration. Typical Site Binding changes might be editing the Port number for a host entry, or adding a new binding for a domain alias.
When it is not practical to restart the server host machine, the alternative process is to restart the server service on the IIS platform – Restart under Manage Website – and also restart the Altium Server Pinger service (a Windows service).
Protocol used for Service-to-Service Communications
SOAP over HTTP.
Service Architecture – Overview
Altium Concord Pro installs a number of core services, as well as browser-based management consoles, and an Explorer (also browser-based). In order to access any of these services, a user's identity must be recognized and authenticated. Altium Concord Pro comes with one predefined user (Username: admin, Password: admin). The Users page of Concord Pro's browser-based interface can be used to add and manage more users. There is no limit to the number of users that may be registered to access and use Altium Concord Pro, but there is a limit on simultaneous connections, as determined and enforced by required licensing.
Altium Designer uses an unencrypted channel (SOAP over HTTP) for communicating with the following services:
- Collaboration Service
- Comments Service
- Data Acquisition Service
- Data Storage Service (DSS)
- Identity Service (IDS)
- Notifications Service
- Part Catalog Service
- Projects Service
- Simple Lock Service (SLS)
- SVN (through the SVN:// protocol)
- Vault Service
All other services communicate with each other.
The majority of services require access to the same Altium Concord Pro database, in which to store data applicable to them. The following are examples of the data stored by some of these services:
- Part Catalog Service - stores supplier and manufacturer items, price and quantity history changes, etc...
- Identity Service - stores users, roles, licensing configuration, and session information.
- Vault Service - stores its structure (folders, items, revisions, content types, lifecycle states, etc...).
Actual documents are stored on the file system, in the Revisions folder (\).
\Altium\ConcordProData\RevisionsProgramData
The following browser-based applications use SOAP API to communicate to the applicable services - they do not require access to the Altium Concord Pro database, nor are any other files required for them to function:
- User Management - the application behind the Users page and sub-pages in Concord Pro's browser interface.
- Vault Explorer - the application behind the Explorer page of Concord Pro's browser interface.
- Catalog Management - the application behind the Part Providers page of Concord Pro's browser interface.
- Projects Management - the application behind the Projects page of Concord Pro's browser interface.
License Files

To manually upgrade Altium Concord Pro to a later version, first uninstall the existing version. This is performed from the standard Programs and Features page (accessed from the Control panel). Right-click on the entry for Altium Concord Pro <VersionNumber> and use the Uninstall command from the context menu.
Once this is done, install the later version of Altium Concord Pro software. Just remember to install with the same settings for data locations and the same communications port numbers.
Re-Indexing Server Content after Data Migration
To re-index server content, for example after data migration:
- Stop all IIS application pools associated to Altium Concord Pro.
- Stop the Elasticsearch (AltiumElasticSearch) service. This is performed from the Windows Services panel - accessed from Window's Administrative Tools window.
-
Delete the content of the
SearchDatafolder, which contains the search indexing data (\for a default install).\Altium\ConcordProData\SearchDataProgramData - Restart the Elasticsearch (AltiumElasticSearch) service.
- Restart the IIS application pools associated with Concord Pro.
On finding the SearchData folder empty, Altium Concord Pro will re-index its content once it starts.
