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. Click Ok to save/enter the new value then exit the registry. DoubleClick the word ' UpperFilters', a dialog will open showing/allowing you to change the Value for 'UpperFilters' there should be no other Values remaining other than PartMgr in this dialog.Įdit the UpperFilters Value to PartMgr deleting any other value in that dialog. When you have found the correct Key (left panel), in the right corresponding panel you will see Data Values for that Key. Now navigate the registry path till you find the Key Bolded above. This is because your registry entry under Win10, in RegistryKey: 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 solution didn't state what to do if it didn't. The activation box did not come up during restart of FSX. This is the closest solution I could find. So my question, how onearth do I activate my very legit installation of FSX and Acceleration? When I go to HELP>ABOUT in the menu it clearly illustrates 'Microsoft Flight Simulator X Demo' Needless to say, that my installation is in demo note. I thought I did that already when I entered the keys. The installation went smoothly, and I entered the product keys for both pieces of software.Īfter 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.ģ0 minutes later I was advised my 30 minute trial had ended and that I must activate the product. I installed both as administrator in a directory outside the Program Files directory. I have just recently reinstalled FSX and Acceleration on my new WIndows 10 machine. I've Googled, but found not much similarity as mine with other users, so let me once again post this question.
