screen stream mirroring error not enough storage available to process this command

ok so im trying to make screen stream mirroring work and i havent been able too. i downloaded the startup tool for non rooted devices . I followed the instructions and when I run the windows batch file the command prompt window says not enough storage available to process this command . I googled that to see if I could find a solution and it said to do this :

To do this follow the steps below:

1. Click on Start > Run > regedit & press Enter
2. Find this key name HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\LanmanServer\Parameters
3. Locate IRPStackSize
4. If this value does not exist Right Click on Parameters key and Click on New > Dword Value and type in IRPStackSize under the name.
5. The name of the value must be exactly (combination of uppercase and lowercase letters) the same as what I have above.
6. Right Click on the IRPStackSize and click on Modify
7. Select Decimal enter a value higher than 15(Maximum Value is 50 decimal) and Click Ok (i changed my value to 50)
8. You can close the registry editor and restart your computer.
