Software Update Required notification

[wadehenricksen]

Starting my first Unity VR project (Vive) with Leap Motion. When I run my project, no hands show up, and I get a succession of Windows 10 notifications declaring:

Software Update Required
An application is requesting features not available in this version of the Leap Motion service. Please install the latest Leap Motion software.
LeapControlPanel.exe

I already downloaded and installed LeapDeveloperKit_3.2.1_win.zip , which was downloaded after I clicked the green "Download Orion Beta" button.The only thing I drug into the scene was the Leap Rig prefab. I also deleted the Main Camera that comes built into new Unity scenes.

I opened up the Button-Builder-master.zip example project scene in Unity that demos cycling between the different hands, and that worked perfectly... but the LMHeadMountedRig prefab included in that Hands_Viewer_Demo is not in the latest (4.4.0 at the time of writing) Core assets. Leap Rig seemed to be the closest fit.

I researched this topic a little and I see other users had "V2" software installed as well and downloading the Orion Beta fixed their issue. I don't think I have ever downloaded the V2 software... just the Orion Beta.

Am I missing additional software to get the hands to show up and suppress the Windows notifications?

There was a major SDK update a few weeks ago, so you need the V4 SDK: https://developer.leapmotion.com/get-started

This ended up being the case. Thank you. The default download button downloads the "beta" older 3.2.1 and I thought it was the latest, given this was not the stable, but beta release. If anyone else who is a Win dev and encounters this, go to https://developer.leapmotion.com/windows-vr/ and make sure to use the "latest installer is available here" link over the big green button.

[AlexColgan]

Can you verify that? The default button downloads V4 from what I can see.

I have experienced a difference in downloads and had more success with the "here" method.

It saddens me that we need to provide what your testers should already know... but
installer "here" resolves to
https://warehouse.leapmotion.com/apps/4621/download
"BETA" button resolves to
https://developer-archive.leapmotion.com/downloads/external/v4-developer-beta/windows

As a developers, we do not need fancy templates and navigation prompts. Here is a useful example from Python:

Welcome to Python.org

Far easier to maintain as well...

The SDK (zip file) includes the installer. They are the exact same download, except the SDK includes documentation and libraries.

We are different from Python in one critical respect -- users don't need to accept our SDK terms and conditions to download the installer, but do in order to use the SDK or our engine integrations such as Unity or Unreal assets. That is the only reason why we offer the SDK and installer, because downloading the installer lets you bypass account creation and terms.

Thanks for your response Alex!

The important thing that we are trying to tell you is that there is a difference in your product's performance when the "button" or the "link" is used. Perhaps it has something to do with how windows handles it... where the libraries get installed.. even Browser security... .I have no idea. Just supporting the observation of the other user. It is a replicated bug for us, which makes it difficult to use your product. We know you are in Beta.

The python page was just to demonstrate a simplified interface for download selection, regardless of the T&C. Beta software has enough problems without installation issues.

[AlexColgan]

I'm confused about what performance difference you're seeing though? Your earlier comment just indicates that the two things lead to two different things with the same software version -- SDK and installer -- which is the intended behavior. OP described the button and the text link giving two different software versions, which is not the intended behavior, and which I haven't been able to reproduce.

[HOTTHANDS]

I am clearing my machine this week for some testing. I will see if this behavior is still happening. We were so frustrated - that when we found the "here" link worked consistently better, we just put it in our machine setup protocol for everyone.

Based on your friendly forum here, I am also going to track the fps and also see if changed settings in the panel stay changed.

As always, Thanks for your assistance!

Can verify that updating to V4 will fix the bug in unity. thanks guys!

[AlexColgan]

What bug specifically?
