CA-Unicenter CCI service failed to start with below error in Services Window:
Windows could not start the CA-Unicenter (Transport) service on Local Computer
Error 193: 0xc1
Release : 12.0
Noticed a file named "Program" on the E Drive (where Autosys is installed) that was preventing the services from starting. This file was put there after the last time the server was rebooted which is why the issue didn't occur until the latest reboot of the server.
Deleted the file "Program" and service started successfully.
With the real folder name being "program files" and as these are older windows modules, presence of a file/folder called program could throw Windows into a weird state, and that explains about the error message "%1 is not a valid Win32 application."
