I have full Administrator account - full access to take permission of files and folders - UAC off etc etc - but gets 90% through install (even right clicked and run as Administrator) then it comes up can't write to reg key even been into registry to the required key and cannot access it to edit or even view.
What codes are you trying to install, Win7 has a lot ready built in is it a codec to paly certain types of files in media center / player i.e. MKV's or FLAC audio files etc, pop over to here click here and look at some of the posts, or alternatley try here click here lots of very useful info on both those sites. Personally don't particually like codec packs but if you have to have one the FFDShow is probably the best, look at the posts in the 1st link about setting up FFDshow.
