[CentOS] Vodafone K4203 Mobile Broadband on Centos7

Hello, 

I hope someone can hlep me take this hurdle towards using Centos7 
I'm trying to get a usb 3-g dongle to work on Centos7 

On Centos6 I can follow the instructions that come with the device to get it to work: 

1. Insert stick 
2. Dismiss all popups about running the auto install scripts 
3. Open terminal 
4. cd $HOME 
5. mkdir vfinstall 
6. cd vfinstall 
7. (cd /media/"Vodafone Mobile Broadband" && tar -cvf - .) | tar -xf <96> 
8. chmod +x autorun.sh install_linux 
9. sudo ./autorun.sh 
10. Type user password 
11. Wait for last command to finish, then close terminal 

or just 
cd /media/Vodafone Mobile Broadband 
./ install_linux 

I also tested the stick on Fedora21, it connects without installing anything. 

On Centos7 I see this:

and the I see this EM:

Further attempts to install the software always lead to EM: 
you must run the install process as root. 

I contacted Vodafone support, their answer is they don't support Linux, even if they supply software for Linux on the Vodafone site. 

Any help would be greatly appreciated. 

Greetings, Johan
