I too have massive problems on getting it to work on my Windows 10 64bit PC. I am stuck in a loop of crashes.
So what happens is, i install the launcher. it installs just fine. i install raid shadow ledgens. and that installs fine. then when i launch the game it always crashes in the video shown at the start. i can never force close the program. the only way to stop the game is to either restart my PC or signing off my user.
When i try to restart the launcher it blinks on screen for a fraction of a second then launcher 5 instances of the launcher in the task manager that i can not force close. only way to shut those down is to restart my PC or sign off user.
When i try to uninstall it it always get stuck at 40% at "deleting temporary files". it then crashes and only way to shut that down is to do as mentioned before.
I then go and manually delete the installed files, redownload the launcher install and the same sequel of events happens again. i tried this at least 10 times and its always the same serial of evvents that occurs.
I did file a ticket about it but all they did was sending out a automated bot response with tips that was not related to my problem
And yes i know i can run it on a different platform like my phone but i just dont want to. i want to run it on my PC as i find mobile games awkward to deal with.
what i have tried is:
re installing it - doesnt work
run lainger as admin - have no effect
run it from safe mode on my PC - does not work
update all drivers - have no effect
my PC spec is:
windows 10 64bit
processor: Intel core i7- 6700k CPU @ 4,00Hz
Ram: 64 GB
GPU: NVIDIA GeForce GTX 980 Ti
