Cant' open script PortableApps.comLauncher.nsi but script is there.

Good morning,

I'm trying to pack my app into a Portable version of it and whilst I setup the dir tree along with some minimal settings in appinfo.ini and in Launcher/AppPortable.ini based on the help pages here in PortableApps.com I can't get the portable apps launcher to create a launcher for my app.

The error is as follows

MakeNSIS v2.46.5-Unicode - Copyright 1995-2009 Contributors

Command line defined: "PACKAGE=C:\Users\catgetitright\Desktop\ApppPortable" /DNamePortable=Appp"
Can't open script "Portable /DAppID=ApppPortable /DVersion=2.2.1.0 C:\Users\catgetitright\Downloads\PortableApps.comLauncher\Other\Source\PortableApps.comLauncher.nsi"


The PortableApps.comLauncher.nsi script is there.

To add, both PortableApps.comLauncher and NSISPortable reside in C:\Users\catngetitright\Downloads\
Any tips greatly appreciated
