Woah. That worked! I'm configuring it now. I hope it works with old MAME v0.177. I haven't updated for years since I don't play games these days. :(

[antdude]

Nullpainter: Try it. Let's keep this one about .NET version issue. #53 for the older MAME version issue that I just made.

[mika76]

Seems to me like it's struggling to run .net? Do you have.net framework 4.6 installed?

[antdude]

How do I know what version I have installed? I know I have .NET, but which version(s)?

[antdude]

Paint.NET uses .NET, and it's fine.

[mika76]

Seems the latest paint.net uses 4.7. I would have thought that would work with mamesaver too. You could always try install 4.6 and see what happens. Shouldn't give a you any problems...

[mika76]

Or maybe you have an older paint.net with an older framework? Here Microsoft's instructions on how to determine which is installed : https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/how-to-determine-which-versions-are-installed

I am using paint.net v4.1.6. BTW, I'm going to sleep soon.

[mika76]

Seems you have 4.7 which should run it without problems. Hmm I'll have to play around with it a bit and see if I can figure it out...

[antdude]

I was able to reproduce it in a clean, updated 64-bit W7 HPE SP1 in a virtual machine (VM) with VirtualBox. Its registry shows:

https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/how-to-determine-which-versions-are-installed says this is v4.6.1. :( Do you have an updated 64-bit W7 SP1? If not, then try it in a machine (virtual is fine to use since I reproduced it).

[mika76]

Hey try and place it in c:\windows\syswow64 and let's see if that's the issue... I'm pretty sure we compile for any cpu but who knows...

[mika76]

They changed the format of their xml output a while ago (don't know specific ver though) so if the build list function doesn't work then it's that and you'll probably need a newer version...

[nullpainter]

I was just about to recommend that! I recall this issue before, but didn't pay much heed to it. We should verify that we are indeed compiling for AnyCPU, @mika76.

[antdude]

Darn it. I can't use MAME64 v0.177 since it didn't find any games. Boo! This will take a while for me to update my ROMs too. Bah!

[antdude]

I'm going to sleep! Thanks! ;)

[nullpainter]

I don't believe it would be too much effort for me to add support for earlier versions of MAME. What are your thoughts?

[nullpainter]

All fixed. PR submitted; will be in next release. The issue wasn't actually about .NET - it was that the screensaver was inadvertently being built as a 32 bit application. Thanks for reporting this, @antdude.

[antdude]

You're welcome. :D
