Running ZCM2017 Update 4.
Started IE as administrator.
Creating Prebbot Bundle.
Adding MDT Action.
Uploading 64-bit WIM (LiteTouchPE_x64.wim). Upload works fine.
In same action, trying to upload 32-bit WIM (LiteTouchPE_x86.wim). Says "Unable to mount the selected WIM file".

I really dont lik to use the 32-bit, but when initiating a remore reimage via ZCC (assigned bundle to device / Apply Assigned Imaging Bundle) , when MDT try to start it says:
"Using MDT bundle GUID: xxxxx
Expected 32-bit MDT wim not uploaded for this applied bundle".
Testing om Virtual machine.

So two things.
Why cant upload 32-bit wim when 64-bit works, and why does it try to load 32-but during PXE, even if machine before was imaged with 64-bit via PXEmenu.
