    I would like to use LM2917 in Multisim but the component is missing.
    I'm trying to make it using component wizard but at some point it asks me for model. I can load a spice model (user defined) from file but only .cir files are accepted.
    I found in this topic LTspice models but they are in asc/asy extension.

    Rename LM29x7.sub to LM29x7.lib. The remaining files are discarded.

    Why .lib?
    It asks me .cir.
    Anyway I tried to load LM29x7.sub renamed as LM29x7.lib.
    It says to me The SPICE file must be a text file. Continue to load this file?

    I select Yes and the model is loaded but when I click Next I get another warning

    Cannot edit the post to add some text.
    It seems that inside sub file there are four models.
    Tried to delete three of them but when clickink Next I get another warning:

    SPICE Netlist Warning, element 'Z68:LM2907-8': Unknow model parameter 'vpk', this parameter will be ignored. Do you want to continue?

    Erase parameter vpk=6.8, it is for LTspice. Reference does not affect the calculation.

    Thanks for help.
    I'm trying to simulate this circuit:

    I don't know if I have mapped pins correctly since inside datasheet there is no an explicit pinout.
    When I start simulation i get a Netlist error.
    I attached the multisim file.
