You could be right that your Product Key is already acknowledged by MS (since 2006), but the fact that you are only able to fly for thirty minutes indicates that your copy of FSX does not recognise that any activation has taken place.   It may be that your multiple re-installs of FSX, or an MS update, etc. may now be giving you this problem.   

You could also check here:  launch your FSX and start a flight, any flight.   Then go to your Menu bar and click on Help and then click on About Microsoft Flight Simulator.   Do you see a Product ID number there (it will be a long series of numbers and this is not your Product Key)?   If there is one there, then that indicates that your copy of FSX is activated.  Those that don't have this number showing, do not have activated simulators.

If after all you have done, you still can't fly for more than thirty minutes (even though you believe that FSX is activated), then my only suggestion is to switch over to FSX-Steam Edition, which is produced by Dovetail Games and is basically FSX Deluxe with the Acceleration pack.  DTG, under limited licence from MS, have updated FSX on several fronts, making it more suitable for later Windows versions.   FSX, in its present form, will probably one day no longer function in later Windows Operating Systems and we will all need to switch over to another Flt. Sim platform.

You can read about FSX-SE, its features (particularly that it is downloadable and no activation key is required!), and its low cost.   https://store.steampowered.com/app/314160/Microsoft\_Flight\_Simulator\_X\_Steam\_Edition/

Sometimes DTG offer it at a Special price.   Other very good Sims are Prepar3d (by Lockheed Martin) and X-Plane, but these are more costly.

Hi,

On my PC w10, I have checked and I have amended the value suggested by Chriso747, but I didn't fix anything.

I think that this activation problem must be fixed by Microsoft directly, because in your system my product key is already activated by 2006.

The activation problem is not in my PC.

note: in my PC w7, I  uninstalled FSX.

Gius.

Hi GenuineAmoeba82,

We would like to know if you already performed the solution suggested by Chriso747?

So I understand that you have two PCs:  one with Win7 and the other with Win10  and you have FSX installed on both of them.  On both computers, FSX launches and you can take a flight, but it runs for only thirty minutes.

As mentioned in my earlier post, the only option you have to fix this activation problem, is to check your Registry and amend the value accordingly.   However, it may be that because you have FSX installed twice, that a problem exists in one of your installs.   You may need to decide which PC you want to run FSX and then go into that PC's Registry and check/amend the value.  Once you've done that and reboot computer, then take a flight and check to see if FSX runs for more than thirty minutes.   If everything is okay, you may then want to do the same with the other computer, but you may run into a problem here since FSX can only be installed on one computer at a time.

I want to specify my problem:

on 2006 I have purchased boxed FSX and I have installed on my PC with XP s.o. After 2 years, I have not played anymore. (This is the PC with Windows 7 s.o. now).

wanting to again install FSX on the a/m PC with Windows 7 s.o., the system said me that the product key has already been activated.

on other PC with windows 10 s.o. (but with the same line router) the system said me the error that I posted with the picture.

In both cases FSX run and I can play, but only for 30 minutes, because my original product key is not activated again.

Thanks 

Gius
