On your Ivanti EPM Web Console, you are struggling to download the piece of software which will let you launch "Remote Control". Hence, you may need to install it manually, and this software is a .EXE file called enurcsetup.exe located on your Core Server. You have also the option to install this software in another language (Ex; In German) in order to open Remote Control in your preferred language.
With the appropriate windows right at a CMD command, navigate to C:\inetpub\wwwroot\Common\
For German (Your OS as to be configured as such), type the following command "Deurcsetup.exe /s /v"LDLANG=DEU /qn"
For English, type the following command "Enurcsetup.exe /s /v/qn" It will run silently with these switches, you can then deploy it to several computers if needed through a batch file to be deployed.
If you look in the directory where these files are, you will see many XXXrcsetup.exe files with a 3 letter prefix for your language.
