I have a stack of n switches, the master is on my preferred version of code 3.6.5, one of the other switches in the stack is on 3.6.6 (shipped from factory).
Switch Ports Model SW Version SW Image Mode

3 56 WS-C3850-48U 03.06.06E cat3k_caa-universalk9 INSTALL
I'm trying to use the software install functionality to downgrade the odd switch out to the same version of code as the master:
# software install file flash:/cat3k_caa-universalk9.SPA.03.06.05.E.152-2.E5.bin switch 3
but I get the following error during the the install:

processing the wcm package on switch 3. Operation aborted.
Memory on device not being enough for preImage download
[3]: % An internal error was encountered. Operation aborted.
It should be noted also, that if I use the software auto-upgrade enable command that the switch believes 3.6.6 to be compatible with 3.6.5 and doesn't try to modify the new switch that is added to the stack.
Note also, I'm not using wireless in the switch itself, nor do I have licenses installed.
Any ideas on how to do this, short of removing the switch from the stack and downgrading this manually?
