I ran another test on PC notebook (Lenovo z-510) always using the version 0.4.3.0. I noticed a very strange thing that I can not give an explanation,
In notebook everything works perfectly without any mistakes and the operation is completed. During processing I checked the folder "C:\Users\USERNAME\AppData\Local\Temp" is filled with files and then generate the files in the folder "WinReducerEX100_v0.4.3.0\WORK\MOUNT".
In the home PC During processing the folder "C:\Users\USERNAME\AppData\Local\Temp" is filled with files but the folder "WinReducerEX100_v0.4.3.0\WORK\MOUNT" remains empty, and shortly after the error message appears. I used the home PC also the beta version which I have recommended, but I get the same error.
I can not give me an explanation for all this is very strange indeed. Thank you for the help you are giving me
