Major Version Mismatch

We have a switch stack of two Catalyst 3750's and are trying to add a Catalyst 3750E.

One of the 3750's is the stack master.

Upon reloading the 3750E it prompts:

%STACKMGR-5-MAJOR_VERSION_MISMATCH: Major Version Mismatch (Local 6 - Received 1) with neighbor-1

and then elects itself the master because it did not join the existing stack.

I did some digging using the show platform stack-manager all command to find out that the 3750's have the stack version number 1.45 and the 3750E has 6.45. This would obviously confirms the mismatch but from what I have read if the systems have the IOS then this should not be an issue and all switches have 12.2(55)SE1.

I don't know if the IOS packages matter to resolve this issue but they are c3750-ipservicesk9-m and c3750e-universialk9npe-mz.

Hopefully this will be a simple fix so I can get the stack up and running quickly.
