Running a rzr1911 installer:

I can get the installer exe to run, I just can't move my mouse within it, even with a USB mouse. If I use a USB keyboard I cannot tab around, but I can hit spacebar and it will install to the default dir of C:\Games\Taiko. Then once that quick install finishes I can hit spacebar again to show the files. It launches it's own windows-based file browser showing the a folder that has the root dir of the linux machine, but separate from that is a C:\ drive(edited) I can double click the game's exe from within that file manager and as it's still part of the proton-launched setup.exe it continues to run the game.exe using the same instance of proton thus the game launches I just don't know where on my SD or internal storage it was installed to, as I don't know how Proton links the linux root folders to a windows C:\ drive I've had no issue with other installers ala fitgirl, but I can move my mouse and change the install dir within them I also tried the STEAM_COMPAT_MOUNTS=/run/media/mmcblk0p1 trick to see if it would default install to the SD card, but it does the same thing. I have a feeling it's installing to a temp dir and once I get out of the installer it wipes that fake dir but as I cannot change the dir within the installer as I have no mouse support, I can't change it to a working dir
