oooh, I see whats happening here.
Both those sceneries we just download an installer, which then installs the scenery. Normally the Manager should open those installers on its own (maybe you have an UAC flashing in your taskbar that you didn't notice?); but if it does'nt here is the path the Manager downloads those installers to:
C:\Users\<USER>\AppData\Local\iniManager\app-2.1.3\resources\app\temp
The Manager will delete those upon closing, so you'll need to download them again π
