# System Requirements

System requirements to run the ERP Connector are basically the same as for the Autodesk Vault Professional client.

* [Autodesk Vault 2025](https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/System-requirements-for-Autodesk-Vault-2025-products.html) system requirements
* [Autodesk Vault 2024](https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/System-requirements-for-Autodesk-Vault-2024-products.html) system requirements
* [Autodesk Vault 2023](https://knowledge.autodesk.com/support/vault-products/learn-explore/caas/sfdcarticles/sfdcarticles/System-requirements-for-Autodesk-Vault-2023-products.html) system requirements

On top of that, you need access to an SQL database to be able to create and send/read the data to/from the Data Interface.

Also, the [Publisher4VLT](https://help.arkance-systems.com/publisher4vlt/) license is mandatory to execute the document publishing process using the ERP Connector.

## Licensing Requirements

* To make sure the licensing of the ERP Connector works flawlessly, whitelist the following addresses in your firewall on port 443:
  * <https://holixa.arkance-systems.com> / [https://licenses.arkance.world](https://licenses.arkance.world/) (web portal);
  * <https://holixa-services.arkance-systems.com> (services).
* The website IP is 13.107.253.67, and the service IP is 13.107.253.45.
* Also, if multiple Holixa-licensed add-ons are to be run on the same machine (this is especially valid for job servers where Publisher4VLT and ERP Connector may run side by side), it is recommended to use a separate user (Holixa) account (e-mail) for each add-on running on the machine.
* Exclude the following folders and their content from the antivirus scan:
  * `c:\Users\!!!USER!!!\AppData\Roaming\Arkance\Licenses\`
  * `c:\Users\!!!USER!!!\AppData\Local\Temp\Arkance\Licenses\`

{% hint style="info" %}
If needed for troubleshooting, the license logs are located in the `C:\Users\USER\AppData\Local\Temp\Arkance\Licenses` directory.
