sideloaded windows 8 app crashing on Windows 8.1 and not installing on Windows 10

I am sideloading a dev package on windows 8.1 and on Windows 10. On Windows 8.1 The app crashes as soon as it launches

Faulting application name: XXXX.exe, version: 1.0.0.0, time stamp: 0x54bd196d Faulting module name: twinapi.appcore.dll, version: 6.4.9879.0, time stamp: 0x54585458 Exception code: 0xc000027b Fault offset: 0x0000000000042bff Faulting process id: 0x1d18 Faulting application start time: 0x01d0359c520d8180 Faulting application path: C:\Program Files\WindowsApps\XXXXX\XXXXX.exe Faulting module path: C:\Windows\System32\twinapi.appcore.dll Report Id: 8fee8d71-a18f-11e4-830a-0050b662bf5b Faulting package-relative application ID: App

And on Windows 10 it does not install saying

error 0x80070020: Creating file \?\C:\Program Files\WindowsApps\XXXXX\Assets\SplashScreen.scale-100.png failed.

Any pointers to the solution would help
