All EtherCAT slave status is stored in system variables you can access as BOOL or WORD. _EC_PDSlavTbl[1] = PDO Status (BOOL) for Slave 1. _EC_SlavErrTbl[2] = Error Status (WORD) for Slave 2. (There's more, but that's what I use as a basic diagnostic check)

Had the same issue on v1.23.  This can also be solved by doing a "Run As Administrator" on the Setup.exe. Looks like a file write permission issue if you're not Administrator on the PC.  I encountered this problem on my PC (Win10 - not Administrator), but NOT my laptop (Win7 - default login is the Admin account).
