PortableApps.com Platform

I have added the application 'Octave' to my USB (in the D:\PortableApps directory). This program does not have an .exe file to start it, the program is started with the file: octave.vbs
How do I do to get this icon in the PortableApps start menu (the "Refresh app icons" does not work for this program)?

Is portable apps only for Windows? Does it work on Mac or Linux in any way?

for example:
Unable to download the file. This could be due to a proxy or network issue or the hosting server not permitting downloads from your location. File: http://portableapps.com/redirect/?s=p&a=ccPortable&d=pa&f=ccPortable_5.6...

Is there a way I can have an "app" that just displays a fixed text message?

So for example I've been using memtest, but Windows has a better memory test built in; so I'd like to replace the memtest app with an app that just shows the instructions for testing under windows.

Similarly for other apps, so I cant just fire up eg AkelPad to show a text file. (tried it AkelPad wont launch if i change its name)

I BELIEVE THIS WORKS ON CHROME

I'm trying to manage my collection of about 150 portable apps
OK I know I can delete them in the platform or from the portable apps folder, but I'd like to sort them by category
And deleting one at a time in the platform would be tedious to say the least.
Does anyone know how the platform maintains its database?

Problem comes from reg value "DarkMode"

According to Webroot software updater 3.5 has a virus and won't allow it to load. Malware group is W32.Malware.gen.

2.44 wasn't recognised as needing updating, appinfo.ini looked good. I downladed 2.45 and installed it over the top.

Should there be a [KeePassProPortable] section in PortableApps.com Updater Database? There isn't in mine.
