If you see this message then it will be when ADE starts and it is almost certainly to do with the ProKey.  Some information is stored by the ProKey third party license code and for reasons that we do not understand, it can throw this message from time to time.  The first thing to try is to delete a folder and try again

The installation package for ADE 1.65 is a zip file that contains  a read me file and an executable installer

The New User Wizard appears, when you start ADE for a specific version for the first time.  ADE does not share settings between different versions.  So, for example, if you have FSX and P3D v1 installed then you will see the New User Wizard the first time you run each of these versions. The New User Wizard will configure Airport Design Editor to work properly on your computer. It starts automatically if it does not find any setting file.

We strongly recommend that you run through the New User Wizard to the end. You can cancel at any time, but ADE9X will not have all the information it needs to work correctly. If you do decide to cancel the wizard before finishing, you can access the wizard any time afterwards by selecting Tools => New User Wizard.

If you need to run the wizard and it does not appear when you start ADE then please open it via Tools > New User Wizard (See Run the Wizard Again at the bottom of this article)

If you install a new production or beta version of ADE it will be in a new installation folder.  The settings and data files in the new installation will be the default ones.  If you have an existing installation you might want to copy the settings and data from that installation into the new one.  Here's how

By default ADE will compile everything in the project file except for those objects that are included for information such as nearby airports and stock navaids.  There is an internal mechanism which works out whether something should be compiled or not.  This is called skip compile not really accessible to the user. The conditions in which something gets compiled can change depending on circumstances and in some cases ADE can't determine whether to compile something until it actually comes to compile the project.

It may be useful sometimes to stop ADE from compiling a specific object or group of objects.  You can do this using Force Skip Compile.  When this property is set ADE will not compile the object irrespective of the internal mechanism.   If this is not set then ADE uses the internal skip compile mechanism.  So settings Force Skip Compile to No is not a guarantee that any object will be compiled.  All you can say for sure is if it is set to Yes then ADE will Not compile the object under any circumstances.

This option is not available for all object groups.  It makes no sense to have it for helper shapes, background images and so on because they are not included in the compile.  It is also not available for the taxi and parking network - it would be difficult to predict the effect of not compiling some part of that.  Finally it is not available for custom GP objects and for Terrain Elements.

Please note that you need a ProKey for Force Skip Compile to be available.  If you don't have a ProKey then ADE will automatically set Force Skip Compile for all objects to No.
