Written forms

遺い憾かんなく
Standard kanji spelling. 遺憾 means 'regret' or 'unsatisfactory', and なく is the adverbial form of ない, so the literal sense is 'without anything regrettable' → 'fully, satisfactorily'.
如何いかんなく
irregular kanji usage
Irregular kanji usage. 如何 is normally read いかが or どう, but here it is used for いかん. Rarely seen; learners should use 遺憾なく.

Etymology

From 遺憾 (いかん, 'regrettable' or 'unsatisfactory') + なく (adverbial form of ない, 'not'). Literally 'without anything regrettable', it came to mean 'in a way that leaves nothing to be desired'.
