I have a C72 with SW Version 16. On the Benq Siemens site there is a firmware upgrade available for SW version 22. The instructions say use the .exe with the DCA-510 cable. "start the downloaded firmware file (.exe) and follow the instructions"

The file downloaded is 12.7MB, but is an unknown file type and not a .exe The MTM utility does not have firmware upgrade option for the c72, but there is for some alternatives.

I am new to Siemens phones. Am I missing something
obvious?

Appreciate any guidance
 
Answered my own question by experiment. Renaming the download file with .exe extension fixes the problem, and the file icon appears.
File runs ok
