License request

Dynamic Systems Analysis Ltd. (DSA) requires that a valid, DSA-issued license file be present on each computer that runs ProteusDS. The generation of a license file requires a two-stage authentication consisting of a user downloading and running the License Request Utility on the computer that is to run ProteusDS, sending the resulting license request file to DSA, and DSA replying with a valid license key.

Step 1 – Download utility on computer that ProteusDS will be installed on

Step 2 – Run utility on computer that ProteusDS will be installed on
Unzip ‘DSA Software Request’ folder to a convenient location. Open the folder and run the extracted executable or batch file. If successful a file called COMPUTER_NAME.dsa_license_request will have been created in the directory.

Step 3 – Email *.dsa_license_request file to DSA
Email the *.dsa_license_request file to

Step 4 – Activate license
After processing your license request, DSA will send you a *.pds_license file. The license file may only be used on the computer that the license request utility was run on.

After downloading and installing the ProteusDS software, open the ProteusDS Simulation Toolbox. Once the toolbox is open locate Help in the top menu bar then Manage License. Next a secondary window will open, locate the license file DSA has sent you then click install.


If you have any issues running the license request utility, please email and let us know your 1) Windows version 2) Administrative access level 3) Firewall / Antivirus software in use 4) Network connectivity.
