At what point will I be asked to activate after launching FSX Right off the get go Or once I commence a free flight I will activate with my Acceleration key or FSX Or both.

This will give you the info you need to get started flying and using.

MSFS Message Forum where you can ask questions and talk about the sim.

I have just recently reinstalled FSX and Acceleration on my new WIndows 10 machine.

I installed both as administrator in a directory outside the Program Files directory.

The installation went smoothly, and I entered the product keys for both pieces of software.

After a few days of reinstalling my scenery and aircraft addons, and configuring all my controls and graphics settings, I opted to embark on a flight.

Flight X Activation Trial Had Ended

I was advised my 30 minute trial had ended and that I must activate the product.

Augh. I thought I did that already when I entered the keys.

When I go to HELPABOUT in the menu it clearly illustrates Microsoft Flight Simulator X Demo So my question, how onearth do I activate my very legit installation of FSX and Acceleration This is the closest solution I could find.

If you followed the procedure and did not get an AccPack Activation dialog when starting FSX then you may have edited the wrong RegistryKey.

This is because your registry entry under Win10, in RegistryKey: 4DE36967-E325-11CE-BFC1-08002BE10318 is not showing as ( P art M gr ) for UpperFilters.

Any other value for this will prevent FSXAcceleration from offering the Online Activation dialog even though you believe you have already activated FSX AccPack.

Flight X Activation .Exe Will Come

On your Windows start menu you will see a search box - type regedit (less the quotation marks) regedit.exe will come up in the list, click to open regedit, same thing if you have the Menu Run box Regedit is the OS utility we need to use to change registry values.

Bear in mind wrongly altering Registry values and Keys can cause boot issues or program dysfunction (Backup your registry before editing - for safety) Navigate or searchfind in your registry this Key: 4D36E967-E325-11CE-BFC1-08002BE10318 HKEYLOCALMACHINE SYSTEM CurrentControlSet Control Class 4D36E967-E325-11CE-BFC1-08002BE10318 Now navigate the registry path till you find the Key Bolded above.

When you have found the correct Key (left panel), in the right corresponding panel you will see Data Values for that Key.

DoubleClick the word UpperFilters, a dialog will open showingallowing you to change the Value for UpperFilters there should be no other Values remaining other than PartMgr in this dialog.

Edit the UpperFilters Value to PartMgr deleting any other value in that dialog.

Now start FSX with your 25 digit AccelerationPack Activation Key handy, once FSX initializes you should be offered the opportunity to re-enter your AccPack Activation Key.

I have followed the instructions of the original Microsoft advice, and double referenced my changes with your instructions in case I missed something.

The reference key in your instructions doesnt match the one in the Microsoft post, and I dont have one that matches yours in my registry.

D E369 67-E325-11CE-BFC1-08002BE10318 vs 4D 36E9 67-E325-11CE-BFC1-08002BE10318 With having followed both sets of instructions (assuming your key might be a typo), Im still not getting the activation option on startup of FSX (even following an computer reboot) and the the About FSX splash screen still showing as Demo.

Having discovered my error you still successfully navigated to the right Key.

Ill see if I can ask a moderator to correct this typo so as not to confuse other readers.

You did the right thing removing those other values from UpperFilters ( fltsrv aswArDisk EPMVolFl ) leaving only ( PartMgr ) as the only correct logical entry, your picture shows exactly what you now have although your cursor is positioned under the word PartMgr and may represent a blank space or new invisible entry.

Try removing deleting PartMgr so that your cursor is in the first position on the panel, then re-type PartMgr without pressing enter or beginning a new line in the dialog, click on the Ok button to apply the value - ( PartMgr ) close the Registry editor restart your PC and then FSX, you will be required to use online activation so make sure your internet is connected WiFi enabled or Ethernet cable plugged in, hopefully this time it will prompt you for online AccPack Activation using your AccPack 25digit licence key.
