Authorise software range (7)
I believe the answer is:
approve
'authorise' is the definition.
(approving is a kind of authorizing)
'software range' is the wordplay.
'software' becomes 'app' (I've seen this before).
'range' becomes 'rove' (synonyms).
'app'+'rove'='APPROVE'
(Other definitions for approve that I've seen before include "Like" , "Give the go-ahead" , "Officially accept as satisfactory" , "Give the green light" , "Think highly of - sanction" .)
