Interface 1bis file not found error

Purchased Interface 1 bis for the ZX Spectrum. 
There are plenty information about it and installing and preparing SD card on manufacturers site https://sites.google.com/site/interface1bis/ 
But I have encountered a problem – could not start it and was allways getting “file not found” error.
Did all steps described in troubleshooting video https://www.youtube.com/watch?v=QYHhWQyVWAU 
Loaded OpSys from PC using LOAD command, program loads OK. But when I do NEW and then RUN I get “file not found” error. 
Solution I found was that I had to repeat all prepare SD card steps, but additionally had to add comparability with Windows 8 (and run as administrator off course) option (I was running Windows 10) to LDCSetup.exe and later to the ‘Prepare new card’ utility.

So, In short – add Windows 8 compatibility to Interface 1 bis utilities.
