Window is cropped and unusable on first launch

[jesus2099]

ConcatPDF is such a cool tool that I have been using for years but some points can make new users not realise it.

First time you want to launch ConcatPDF, it is not very obvious for the GUI users that they should double-click ConcatPDFW.exe.

And then when they launch ConcatPDFW.exe for the first time, the window is cropped and unusable:

Because HKEY_CURRENT_USER\SOFTWARE\Ujihara\ConcatPDF and its WindowHeight and WindowWidth do not exist yet.

Default values should not be 0 but something like 600×400.

It would be nice to change this and to regenerate bin zip file with the new version properly to not lack any DLL (#2), so that new uesrs are not turned off.
