Well, you have the hash string "MWw4MjlrM2loajFz:qu0VLHJPa2dNL6+7bRIpcRGcdInpFO6B5OGMgnyEeyM=", we assume the first part is the salt and the second part is the hash. Just convert it from base64 encoding to hex encoding:
Then combine them in hash : salt format and run with --hex-salt.
Code:
epixoip@token:~$ echo MWw4MjlrM2loajFz | base64 -d | xxd -p
316c3832396b3369686a3173
epixoip@token:~$ echo qu0VLHJPa2dNL6+7bRIpcRGcdInpFO6B5OGMgnyEeyM= | base64 -d | xxd -p

Then combine them in hash : salt format and run with --hex-salt.
Code:
./oclHashcat64.bin -m 1410 --hex-salt aaed152c724f6b674d2fafbb6d122971119c7489e914ee81e4e18c827c847b23:316c3832396b3369686a3173 -a 3 CieloAzzurro.1
