Can't use .bat to install game on Android

Why can’t i install the game on my phone using the .bat file?
When i package the game for android, it comes with a .bat install file, so i can install the game on my device

HOWEVER…
When i open it, it gives me errors:

Here’s the text:

There was an error installing the game or the obb file. Look above for more info.

Things to try:
Check that the device (and only the device) is listed with "ADB$ devices" from a command prompt.
Make sure all Developer options look normal on the device
Check that the device has an SD card.
Press any key to continue . . .

What device am i using?
I’m using a Samsung Galaxy S8. USB Debugging is on, and my device is recognized when i use the adb devices command in Powershell. it does not contain an SD card, i am using Internal storage only (64GB)

So what’s the problem?
Really appreciate if someone can help me out. Thank you.

I’m facing the same issue with some variation - this is on a Galaxy Tab A

Possible solution: DELETE_FAILED_INTERNAL_ERROR when deploying to Android - Mobile - Epic Developer Community Forums - (didn’t work)

Solved the issue. I had to uninstall the android studio/nv pack and delete it, and download a fresh install of it, and install the required API levels again, and the .bat file is now able to install the game on my phone!

I’ve been trying to install UC Mini from http://ucminiapp.in/ is it safe to make changes if we got source code? Thanks!
