IsDotNETInstalled in the version 2.19 ?

dear all

I have just read the release notes of the version 2.19 of NSIS. It is written : simply version of IsDotNETInstalled.. which include to use it ?
thx by advance..

I am glad to see that the breton language is taken into account in NSIS from the version *.13.... 🙂

There's no include file for it. The link to the function in the documentation contains the code itself.
