I just upgraded to 9.6SP2 from SP1 after seeing that it was supposed to fix the disconnected USB creation issue, but I am still having issues. Creation fails at copying over my image files. My provisioning log simply says
INFO copying imagefile to USB drive.
ERROR Could not process Template
I'm doing it directly from the from the Core machine, however, our machine is in a VM and I am connecting to that remotely and mounting the USB in VMware from my remote computer. Plugging the USB into the VM host directly makes no difference.
I followed the community video on how to create offline templates so I'm not sure what I'm missing. I captured a split .tbi file that are 2GB max file size, drive is FAT32, the images are on my preferred server, the UNC path is correct and accessible, I've checked the self-included agent installer. I don't know what else to do!
