Hey Marukuru,
I do not know, if you will even read this question but..... However I have also Linux (Ubuntu) running on my computer and I have the same problem that I cannot open the EZ-Flash-V-Client. I installed Wine on my computer but when I try to open it by typing " wine EZ4_Client.exe"...
I feel like school, back when I was actually in school, was more entertaining though, because of how much I get to interact with people, hang out with friends, and other stuff like that. All I get to talk to at work is my boring coworkers lol
