i built it manually. extract that 3 files from the wmp11 installer and then built the .ini and the .inf files. added also the tweaks. and then i cabbed everything. that is all.
well the regtweaks are not really needed..... and the error u getting cause some files werent registered properly.... u can use nlite to remove all wmp 6.4 and 9 but keep wmp compatibility and add the pack.
no problems here re download ryans pack cause it seems that there were problems downloading and u might got an uncomplete one.... then after the download verify the size and md5 hash.....
its simple: just unpack the addon and look at the runonce.inf. u will find the switches there..... dont get upset i dont post them but i am lazy .......
if u dont have the xpcd or a internet connection, u cant help yourself.... it seems that your instalation is broken so i say to do a fresh one with wmp integrated. u can use my addon found in my signature.....
