Kapur, who won the season's opening Challenge Tour event in India, finished at 11-under 277 after rounds of 70, 71, 71 and 65.
Last fortnight Kapur made the cut at the Open Championships at Muirfield after leading at the end of the front nine on opening day.
Stuart Manley marched to his maiden European Challenge Tour title at the Finnish Challenge as a clinical final day performance earned him a three under par round of 69 and a two-shot victory.
Manley's win moved him to seventh place in the Challenge Tour Rankings and now he believes he has the confidence to go on and secure one of the all-important 15 European Tour cards on offer at the end of the season.
Three shots further back in tied third place were Englishman Jamie Elson, who carded a four under par 68, and Swede Jens Fahrbring, whose level par 72 earned him the best result of his Challenge Tour career.
