windows 10 ( 64b) with cura cannot identify the printer

[guy1a 0]

hello

 

i have a laptop by lenovo ideapad 320, with windows 10 64b, i can install cura fromthe old versions like 15.04 and run it without any problems. 

but cura from the more new versions 2.x and up .. installs fine but never could connect to the printer.

 

i have a wanhao i3 duplicator.

 

i tried all the ways i found here and on google .. installed and reinstalled drivers .. but no help.

even if i have both versions installed together .. the old one work fine, the new give me only to save the file.

 

i saw that the last ver 3.5 has the wanhao printers in the list ( same settings as i entered myself .. ) and thought it may work this time .. but not.

 

is there a way for me to use the cura with modern versions on my computer ? i really want this.

 

i may add that i have few arduino boards i use for home projects .. all of them connect easily to the same computer.

 

if there is any other information i can provide to help you help me .. please tell me.

 

thank you
