irun is not recognizing .scs files

I am running ams irun simulator Cadence IC6.1.6-64b.500.2

I get the following error:

irun: *E,FMUK: The type of the file (./spiceModels.scs) could not be determined.
irun: *E,FMUK: The type of the file (./amsControlSpectre.scs) could not be determined.

The contents of the two files look quite normal to me.  Here are the contents of amsControlSpectre.scs

// This is the Cadence AMS Designer(R) analog simulation control file.
// It specifies the options and analyses for the Spectre analog solver.

simulator lang=spectre

simulatorOptions options temp=27 tnom=27 scale=1.0 scalem=1.0 \
reltol=100e-6 vabstol=1e-6 iabstol=1e-12 homotopy=all limit=delta \
gmin=1e-12 rforce=1 maxnotes=5 maxwarns=5 digits=5 pivrel=1e-3 \
checklimitdest=psf

tran tran stop=1u save=none write="spectre.ic" writefinal="spectre.fc" \
annotate=status maxiters=5

finalTimeOP info what=oppoint where=rawfile

modelParameter info what=models where=rawfile
element info what=inst where=rawfile
outputParameter info what=output where=rawfile

Running with spectre alone works fine.

I checked irun documentation but don't see where I can define extensions for spectre files, just veriog/systemVerilog/etc. files.

    Hi Eric,

     It looks to me that you are using a very very old incisive version where irun does not support .scs file. You can find the irun version you are using either at the top of the irun.log or if you do 'irun -version' in the UNIX terminal.

    The .scs files are supported in IUS 9.2 (which is also a very old version)  & onwards. 

    So if that's the case (an old version is being used) please move to a latest one. The latest incsive version is INCISIVE 15.1

    Regards,

    Dimitra

    Thank you.  This was extremely helpful.  It turns out that there was an old INCISIVE version buried in the directory structure, and it was included in my $PATH.  Fixing the path to only include the new INCISIVE version fixed the problem.
