mmsim72: licensing issue

Hi all,

I installed cadence ic6.1.3.1 and mmsim 7.2 for the first time. I installed them in a server to be logged in from remote workstations through the LAN. The user .cshrc files are enriched by the following lines:

set OA_HOME = "/usr/local/cadence/ic613/oa_v22.04.028"
set CDS_ROOT = "/usr/local/cadence/ic613"
set MMSIM_ROOT = "/usr/local/cadence/mmsim72"
setenv CDS_LIC_FILE 5280@CDNSServer
setenv LM_LICENSE_FILE $CDS_ROOT/share/license/license.dat
setenv SPECTRE_DEFAULTS -E
setenv CDS_Netlisting_Mode Analog
setenv CDS_LOAD_ENV CWDElseHome
setenv LANG C

set path = ($XPath $unixPath $machinePath $opusPath $CDS_ROOT/tools/bin $CDS_ROOT/tools/dfII/bin $MMSIM_ROOT/tools/bin $MMSIM_ROOT/tools/spectre/bin)

My problem is, after the creation of the netlist of the schematic circuit, my simulation halts in the following warning:

Notice from spectre.
    Waiting for available license for Virtuoso(R) Spectre.

I think, the problem is not within my license, rather in the configuration of the license, because i can simulate with mmsim62 simply by changing set MMSIM_ROOT = "/usr/local/cadence/mmsim72" to set MMSIM_ROOT = "/usr/local/cadence/mmsim" , where mmsim is a symbolic link to the mmsim62 where it is installed. MMSIM62 was installed before and I have no idea how it was configured.

 Anyone please suggest me how to fix this problem.

Do I have to copy the license to $MMSIM_ROOT/share/license ? I edited the first two lines of $CDS_ROOT/share/license/license.dat, but did nothing in $MMSIM_ROOT/share/license.

Or, do I have to create any symbolic link within the installation directory of mmsim72, for example for tools.lnx86 ? I created none.

Is there any constraint that, the installation folder must be named as mmsim ? I installed in mmsim72.

Please, give me any clue for the problem. 

Thank You,

Regards
