Zam Posted November 14, 2021 Share Posted November 14, 2021 So this is the first time I'm even attempting to use Launchbox at all and the software simply refuses to work. It asks me to download the .net stuff, So I do that and install both the x64 and x86 versions. But Launchbox keeps asking me to install them when I already did that. I even checked to see if I downloaded the correct version number and it's 3.1.0. It just refuses to work. Quote Link to comment Share on other sites More sharing options...

If you try to run the installer, do the dependencies not install for you? Also, here's a link to the correct .NET Core installer. You'll need to choose .NET Desktop Runtime 3.1.21, the x64 version (more than likely, although it may be worth finding out whether you have x86 or x64 version of Windows). https://dotnet.microsoft.com/download/dotnet/3.1 Quote Link to comment Share on other sites More sharing options...
Zam Posted November 15, 2021 Author Share Posted November 15, 2021 No. I've tried reinstalling, but whatever dependencies it needs is simply not being installed for some reason. I have also tried installing 3.1.21 but that doesn't work either. I use 64 bit windows 10, but I installed both versions just to be sure. Launchbox still insists that these are not installed.

C-Beats Posted November 15, 2021 Share Posted November 15, 2021 I would try running Command Prompt as Administrator and running "/sfc scannow" (Without quotes) and letting it run then restarting your computer. Sounds like the OS data that tells us you have the runtime installed has been corrupted or isn't working correctly. That process should correct.

artician Posted January 8, 2022 Share Posted January 8, 2022 Hi, I'm having this same issue. Launchbox claims it needs ".NET Core 3.1". I have installed: - .net framework 4.8 - .net desktop runtime 3.1.x - .net runtime 3.1.x - ASP .net Core 3.1.x I see this dialog when I install Lanchbox 12.5. I did not try other versions, but if I go back to LB 10.1, I think it actually works. I would double check that, but... When I followed @C-Beats suggestion (which I think has a typo; the '/' should precede 'scannow'), the process said it found and fixed errors. I rebooted my system and the explorer.exe process will launch, eat up 6 GB of RAM, crash, relaunch, and repeat. Didn't expect this! I just reinstalled the OS (Win7) on this tonight, so starting over again is not a big deal, but if you have an suggestions about fixing the .NET Core 3.1 issue please share. What else could be the cause of the issue? Why does LB 12.5 need this, but 10.x doesn't? Thank you for your help and suggestions. Quote Link to comment Share on other sites More sharing options...

Or .NET Framework, .NET Runtime, or .NET Desktop Runtime? Those are all listed beneath the only link on Microsofts site that refers to anything named ".NET Core", and there is no individual download with that name. I have installed *all* of the distributables in that section, both specified versions and latest versions, of the site except the SDK itself. Sorry I have to rely on this community to clear up Microsofts messes, but this also seems to be clearly a bug with Launchbox. Even if I let Launchbox automatically download the version it says it needs, the issue still persists after installing that version (which is almost certainly the same among those I've installed manually). I am running this on Win7x4 on an HP TouchSmart 610-1130y. OS was freshly installed. The system is a dedicated MAME machine. Thank you for any additional help you can give.

C-Beats Posted January 9, 2022 Share Posted January 9, 2022 You just need the .NET Core 3.1 Desktop Runtime found here: https://dotnet.microsoft.com/en-us/download/dotnet/3.1 (right hand side, middle bit) Quote Link to comment Share on other sites More sharing options...
artician Posted January 12, 2022 Share Posted January 12, 2022 (edited) Great, thank you for confirming! Okay, since I already had that installed, what should I check next (since it's still giving that message). I had installed 3.1, 3.1.6, and 6.0.

artician Posted January 24, 2022 Share Posted January 24, 2022 I'm going to bump this since it was never actually fixed. I got my system up and running with LB v10.1 again, but there are still issues with that situation that would be resolved by installing a later version of the software. In order to do that, I need to figure out the problem with its recognition of its own requirements. Quote Link to comment Share on other sites More sharing options...
peacock93 Posted February 2, 2022 Share Posted February 2, 2022 I have this problem as well. Anyone have any advice on getting past it. I use LaunchBox on Android and it works perfectly so I decided to put it on my laptop and can't get past this issue. Thanks for any help anyone can pass along!

artician Posted March 26, 2022 Share Posted March 26, 2022 (edited) Bumpity Bump. I got a whole new gaming rig. Installing Launchbox 12.5 has the same issue as reported above. Here were my steps: - Install Win10 - Set up all the things (typical process, can share details but should not affect this issue) - Install Launchbox 12 - Launchbox setup informs user that .NET Core 3.1.6 must be downloaded from the internet for Launchbox to run - Quit Launchbox setup - Install .net-runtime 3.1.6 - Install .net framework 4.8 (included with Win10) - Install .net desktop runtime 3.1.x - Install ASP .net Core 3.1.x (all the versions of .NET I can find) - Install Launchbox 12 - Launchbox setup does not inform user of need to download .NET Core 3.1.6, and Launchbox installs as expected - Launch Launchbox - At startup Launchbox prompts the user that .NET 3.1.6 is required to run, and asks if the user would like it downloaded now This is kind of silly. As with all my gaming rigs, this is an offline machine. Can this issue please be addressed? I am moving to download the latest version of LB now, since I now have no choice but to run Win10, but... Thank you for any assistance. Edited March 26, 2022 by artician .net version correction Quote Link to comment Share on other sites More sharing options...
artician Posted March 26, 2022 Share Posted March 26, 2022 Update *SOLVED* So it turns out another post elsewhere recommended just installing the SDK. When I installed the SDK on my Windows 7 rig, the issue did not resolve. When I installed the SDK today on my Win10 rig, the issue was resolved! 🥳 <3 Quote Link to comment Share on other sites More sharing options...

It's basically tools for devs to develop software, and since Launchbox is built on .NET, its needs these tools to run.

C-Beats Posted April 4, 2022 Share Posted April 4, 2022 LaunchBox does NOT need the SDK to run, only the runtime. SDK is used to create and compile applications using .NET Core, runtime just has all the code that those programs require to operate on your machine.

C-Beats Posted April 4, 2022 Share Posted April 4, 2022 Meh you were half right at least. That IS what "SDK" stands for and what it's use case is. 1 Quote Link to comment Share on other sites More sharing options...

MooseXP Posted August 16, 2022 Share Posted August 16, 2022 (edited) For LaunchBox version 12.14, it requires these dependencies: Visual C++ 2015 Redistributable - https://www.microsoft.com/en-ca/download/details.aspx?id=48145 .Net Framework 4.8 - https://support.microsoft.com/en-us/topic/microsoft-net-framework-4-8-offline-installer-for-windows-9d23f658-3b97-68ab-d013-aa3c3e7495e0 (offline installer version) My machine already has .Net Core 3.1 installed, so not sure if this is in addition or not. Attached is a screenshot of the LaunchBox install dependies. Edited August 16, 2022 by MooseXP Quote Link to comment Share on other sites More sharing options...
