Tried to add a 3750 to an existing 3750 stack got a message like: "A switch with incompatible software has been added to the stack. Scanning found no software to make all 3 compatible..."


Switch         Ports  Model                     SW Version                        SW Image            
------   -----  -----              ----------              ----------          
*    1   12      WS-C3750G-12S       12.2(25)SEB4            C3750-IPSERVICES-M  
     2   12      WS-C3750G-12S       12.2(25)SEB4             C3750-IPSERVICES-M  
     3   0        WS-C3750-48TS        12.2(25)SEE2             C3750-IPBASEK9-M    

Switch#  Role      Mac Address     Priority     State
--------------------------------------------------------
*1       Master    0015.fa23.2500     1         Ready              
 2       Slave     0015.fa23.3600     1         Ready              
 3       Slave     0018.19b3.6280     15        Version Mismatch

Crypto software causing the problem? or is it IP base vs IPservices?

There are potentially both hardware and software incompatibilities.  Take a look at  http://www.cisco.com/en/US/products/hw/switches/ps5023/products_configuration_example09186a00807811ad.shtml in the sections on hardware compatibility and software compatibility.

The last switch needs to be upgrated to IPSERVICES, NOT IP BASE. IP Base will not have all the features of the other two. Put is at the same version to be safe also.

You can mix and match software types in a stack, but not versions. In my office I have a stack of 6. 2 with IPSERVICES and 4 with IPBASE, but all are running the same SW version.

In your stack 1 and 2 are using 12.2(25)SEB4 and 3 is using 12.2(25)SEE2. These all need to match for the stack to work correctly.

Actually,
  Your Master switch should push it's Image to the slaves which is one of the selling points of stackwise. The problem is the SW image.
