Replace rlm.exe and rlmutil.exe in the license directory (C:\Program Files (x86)\AtaiTec\License).
Make the license directory have read/write permission if it does not have already.
Start rlm.exe
One main difference between RLM11.1 and RLM15.2 is that username and password are needed to access the web server (through http://ServerHostName:5054). Open http://ServerHostName:5054 and sign in with username: admin and password: admin
Change password for admin
Edit rlm.pw to add users with blank password and proper permission ( – see License Administration Manual.pdf in the .zip file for more details)
