The L-1011 panel/simulation INS is the same as that featured within our B707, B727-200, CV-990A, DC-8-50/-60/-70, and DC-10 panels/simulations .... those among these other panels/simulations that are INS equipped as not all of these are intensionally.
This INS system has been avialable since 2006/7 .... and been perfected a number of times over time.
The last L-1011 panel updates were applied during December 2018 .... but these edits were only in relation to WX Radar improvements since nothing else, at all, was edited.
The only reason for this INS to not function properly is if it´s not been programmed correctly to start with and in relation to other panel related navigation settings.
I note you state you´re "familiar" with how INS should work .... and that´s fine .... BUT .... Are you familiar with how "this particular" INS needs to be programmed ?
Rather than stating "it doesn´t work" .... it would be better to state .... and step by step .... "precisely how you´ve been trying to program the INS"
Kindly do this please .... as it would be far more helpful to those trying to analyse your issue in the hope they can possibly then identify "precisely what step you´re performing incorrectly or what you´re otherwise doing wrong" .... and then advise accordingly.
In the meantime and as a start only .... I recommend you study both of the following HJG INS tutorials ....
i allready read the thread about this INS but you cant switch the switches or push the buttons. and now i go see this tutorial video. Sure it will be a tiny litlle thing but keeps me busy for a few evenings now . I come back later.

I seem to recall .... that knob may need to be "depressed" .... and for up to several seconds in order for it to be able to function.
FYI .... I have (a couple of days ago) messaged our INS expert to assist you .... "when he´s available to be able to do so" .... so .... if you´ll continue to check in here and kindly bear with us (until he is available) then that´ll be appreciated.

Looks like I was right about "holding down/depressing" the MSU knob (for over a second) .... based on another similar MSU query I recalled in relation to the same INS system which is also featured in our DC-10 panels.
In response to this earlier forum posting .... George CARTY (the author of the INS featured in our B707, B727, CV-990-A, DC-8, DC-10, and L-1011 panels) advised as follows ....
You'll need to hold down the left mouse button for just over a second when changing the INS MSU selection between OFF and STBY or between NAV and ATT: this simulates the additional effort of moving between these positions (that on the real MSU involves pulling out the knob).
Employ the above advice .... for starters.
Refer to the posting by "CLAUDIOFALCAO" .... dated "August 19th 2019" .... within the following linked thread ....
.... and follow each of the several successive postings until the end of this thread as this misundertanding was resolved
If that´s not successful (and there´s no reason why it shouldn´t be) then await the advice of our resident INS expert .... as requested within my last posting.
Again .... there´s no known issues associated with this INS in any of our panels equipped with it .... so .... your experience is likely just a matter of becomming adapted to it .... based on your reporting to us and the advice we provide accordingly
`Programming the INS is no problem any more but the a/p is not following the INS.
after take off i engage the autopilot to reach the heading and altitude `, when a/t says use own navigation i push the INS button. In the hsi i read INS but also a red nav flag. This is my first INS programmed flight with this HJG l1011, am i missing a step here? a/p is on, heading is on, MSU on Nav position

A couple of questions and a couple of things to try.
First, when you enter in the coordinates, are you rounding up or down the last decimal of the waypoint as you enter it? For example KMIA is N25.47.33 W080.17.26. You have to enter that into the the CDU as N.25.47.3 W080.17.3 rounding off the last place. The CDU May change the last digit after you enter it in, but that’s ok.
Second, the FROM TO window in the CDU should say 01 before you pushback. If it doesn’t, click on WPT CHG enter 01 then insert. You will have to have the Mode Selector in any mode except WPT in order to do this.
Now go to the main panel and on the glare shield you should see a button illuminated in yellow/orange RADIO. Click this button to change it to read INS. This changes the HSI from radio inputs to inputs from the INS. if you click it again it will go to the GPS then one more time back to RADIO. You should notice that the HSI will now point to the track to the next waypoint in you INS if you have it selected to INS.
You will need to make sure that you have selected AUTO on the CDU not MAN so that the INS will automatically click over to the next waypoint as you overfly the previous one.
After take off, make sure that the radio navigation button has INS selected and when ATC tells you to proceed on course, hit the NAV button on the autopilot. I usually fly in HDG mode until I am just about to intercept the HSI course.
It can also be good practice to make the first waypoint in your plane about 20-30 miles on course so you don’t accidentally miss any waypoints while being vectored by ATC.
