Upgrading VM From v17

Question

Hello There ! 
 
 I encounter an issue when I want to Update my XG to v18. 
 Environment : 
 - 2 CPU 
 - 4 GB of RAM 
 - HDD : 40GB 
 - Running Version : SFOS 17.5.8 MR-8 
 - Platform : VMware ESXi 6.0.0 
 
 What I dit : 
 - I've downloaded the package : VI-18.0.0_EAP1.VMW-102.gpg (I also tried with the SW-18.0.0_EAP1.SFW-102.gpg) 
 - I Use the SFLOADER in order to upload the new firmware 
 - I'm able to upload the package on my XG 
 - I choose the firmware I want to overwrite (I tried with both) : 
 
 - When I want to validate it, I've got the following error :

How can I update the fwloader ? 
 I didn't found any repository to download it. 
 
 Do you already encounter this issue ? 
 
 Thanks

Not sure where to upload the loader, but you should be able to get the ISO and just burn it to USB and plug it in. That's what I used. Reboot, and the installer will handle everything. It will wipe everything on there so be careful. Have a monitor and keyboard plugged in.
