How do I reserve licenses for certain users?

kbadmin — Thu, 29 Jan 2026 00:06:12 GMT

If you have a RLM Cloud license either concurrent or named user, you may wish to reserve a license seat to always be available for a user or group.

To do this in RLM Cloud login to your admin portal here https://ls53.rlmcloud.com/rlmcloud/rcc_dashboard.php (If you do not know your login contact licensing@dataminesoftware.com for assistance)

Go to the Dashboard tab and click the options button for your server

Then to reserve a license add a line below the comment such as

RESERVE 1 DiscoverArcGIS Username

where username is their Window's username (do not include the domain/company prefix).

Save the options file, and then back on the dashboard tab, click the Reread button which restarts your server and applys the options file changes.

More details on the various settings you can control in the options file are here https://docs.reprisesoftware.com/docs/admin/isv-options-file.html#

Unable to connect to Discover for ArcGIS Cloud Licensing error -17

kbadmin — Fri, 03 Oct 2025 03:44:57 GMT

Occurrence

I am trying to connect to a cloud license but receiving a Communications Error (error code -17)

Solution

Firstly double check your Client ID and Password are correct.

If this is correct, then check with licenseing@dataminesoftware.com if you license server is running and the license isn't expired.

Lastly, it is possible this error is caused by network unable to connect to the licnse server. Check with you IT if you need to whitelist the URL or access to the https://ls53.rlmcloud.com and Https://rlmcloud.com.

If possible try a different internet connection to activate on, i.e. hotspot your smartphones mobile data, and connect to its hotspot wifi. Or If possible take your laptop home or to a cafe public wifi connection to try and activate, and then take the license offline to use.

It could also be possible that local antivirus software may have firewalls blocking access to certain urls. Check with your IT on instructions on how to either temporarily disable this, or if URLs need to be possibly whitelisted.

How does the Discover licensing connect to the cloud?

kbadmin — Thu, 29 Aug 2024 06:27:31 GMT

All license models now use HTTPS (port 443) to connect to the cloud licenses servers.

If you are in a highly restricted environment, your IT may need to unblock the following -

Allow ArcGIS Pro to connect to the internet on port 443 -

C:\Program Files\ArcGIS\Pro\bin\ArcGISPro.exe

And'whitelist' the URLs -

http://hostedactivation.com/

https://ls53.rlmcloud.com/

What are the different license models available?

kbadmin — Fri, 19 Jul 2024 06:10:56 GMT

Discover for ArcGIS Pro offers 3 license models, all are subscription based and will be issued with an expiry date, after which they cannot be used.

1. Standalone

This is a traditional license that is activated and locked to a specific computer hardware. It requires an internet connection to initially activate, but afterwards does not require a connection and can be used offline.

The license can be returned via the internet to the Datamine License server, and it will be released and available to activate on a different computer. There is no limit on how many times this can be done.

If the license is 'lost' due to hardware failure or reset, it can be deactivated and released by Datamine support.

A single activation key can be used to activate multiple licenses, so a company only needs 1 key for multiple users. An admin can access a customer portal, to view who has activated it. And the last time the user has opened the software.

The cloud concurrent license in Discover for ArcGIS is a traditional floating concurrent license model. However it is hosted on Reprise's cloud servers, so no on premise server is required.

Each customer's server is maintained in its own instance, and only accessible by a company name and password that each user's connects with. All communication with the server is via HTTPS port 443.

The server supports all the standard license administration functions by a secure customer portal. Such as viewing usage, revoke, roaming ( take offline), reserving license to users and groups, and detailed usage logs.

Note as this is a Cloud server license, you must be online with a internet connection to use the licence. You must take the license offline, before going offline, to continue to use it.
