I don't know if this is a problem with my system or a bug in the installer, but I thought I'd point it out.

That's strange. I created the installer using the open source Excelsior installer, and tested it before uploading. It created a desktop icon, and inside the menu group there's the uninstaller and the actual program. I'm also using Windows 10 on this machine. Perhaps uninstall and try again?
If not then I'll have to perhaps start using a different installer creator software.

I struck the same issue on a Vista-Home Premium SP2 (32-bit) as Eric did, that I merely have the uninstaller in the newRPL Start directory. The behaviour seems to be the same in that it simply doesn't create the desktop icon, nor put the executable into the Start->newRPL menu group alongside the uninstaller. Thankfully the group doesn't get removed after first view, like some instances of Win10. Perhaps yet another reason to stay away from Win10.

Here are the steps I did to reproduce the problem:
  • Start installer. When asked, feed it with a path to install to; here, that's E:\newRPL Desktop.
  • When asked for program group, provide this: HP-Emulators\newRPL Desktop 0.9aAlpha.

The rest of the steps are (relatively) obvious.

For the current documentation, I'd also like to suggest a wiki link in the first post, as I missed the link until way further down the thread. The first post would be a fantastic place to have this information alongside the links you've already provided, as the wiki provides several very important pieces of information such as the revamped menu interface (which I have a bug I want to post against that, or a misunderstanding). I'll post my thoughts on that menu thing tomorrow, as it's fantastically late here where I am at the moment.

Now, onto the desktop application you've helpfully provided. It's a great way of testing it all out without blowing a running HP50G's setup away, but I got stuck by one small issue. All that got installed on my system were: libgcc_s_dw2-1.dll (no version), libstdc++-6.dll (no version), libwinpthread-1.dll (, QT5Core.dll (, QT5GUI.dll ( and QT5Widgets.dll (, newrpl-ui.exe, Uninstall.exe and platforms\qwindows.dll ( When I tried executing newrpl-ui.exe, Windows barfed up and said this:

This application failed to start because it could not find or load the Qt platform plugin "windows" in "". Reinstalling the application may fix this problem.

It seemed I needed to install a version of QT, as the version you released wouldn't work on my system without me running windeployqt.exe from my QT install against the newrpl-ui.exe and letting it copy my QT's dlls into the same directory. Perhaps an extra page talking about what to do for the desktop application in the wiki.

I'm slowly getting used to newRPL, I don't feel confident enough to spring for another HP50G, but experimenting with it on the desktop feels "right" for me. Good luck, I can see this going a long way.

Cheers, brickviking (a.k.a. DrSmokey)
