I have been trying to install Lamento for a few days now, but no luck. Trying to run the game results in a new blank window opening for a split second before immediately closing.

I've tried multiple different downloads, installed and patched the game right on my C: Drive, running it after putting boot.iso and the lamento iso in together; tried running it with the NoDVD exe, installing and starting in compatibility mode, with or without the english patch - It just repeats the above problem, no error messages.

I'm on windows 10. My system locale is on japanese, and I tried switching back to native and then back to japanese. I installed a bunch of other games along with Lamento, and they all start and seem to run just fine. Lamento (And Togainu no Chi, for that matter) are the only games I'm having trouble with. Any ideas?
