i installed the net framework 1.1 and its sp1. But after do it, xmplay still asking by the library. So i am not sure that net framerwork works fine.
like i said, i have placed the 'msvcr71.dll' into 'syswow64' folder of the win8.1
XMplay never more asked about it.
so i dont know what more i can do, but yes, when we click config button i remember in xp that all the plugins are browsing, or some like that...
Anyways, i remember some messing yes with Milkdrop and some registering dll into its files etc. It may be the reason... i will check one by one all the winamp plugins i have.
