I gave an old PC to a friend xp running Nero 9 for some reason when attempting to burn a data disc and adding files we cannot select any files or folders the usual explorer options of my documents etc has been replaced by a tiny window when we click Add files the tiny window gives no options to select any files whatsoever I tried installing nero 7 essentials and it does the same thing tried restoring windows explorer settings back to default no luck when I type in the file area "my documents" or anything it says not found at the moment nero 7 essentials is installed because 9 won't install properly it's a wobbly OS - I might consider a repair install or else a complete reinstall of OS but in the meantime just want my friend to be able to burn files to disc explorer is otherwise normal outside Nero
Try installing and running this program to see if it repairs all your problems with Windows XP.It fixed all the problems I had with my PC. http://www.tweaking.com/content/page/windows_repair_all_in_one.html
imgburn will get you up & burning until you get nero sorted. As for nero i'd run their uninstall tool to get rid of all versions & then reboot & run it again to be sure then use ccleaner's registry clean button, however it sounds like windows registry has become corrupted or perhaps missing critical files nero needs to run correctly then again you say the OS is wobbly if that's the case adding more software to an all ready buggy computer will only make it worse, now would be a good time to reinstall & use the free app easeus todo backup to start making system backup images it'll make things better in the long run..good luck
thanks for the advice everything noted. in the short term I'll look for IMGBurn and wait for him to do a complete reinstall I did run CCleaner but I'm not 100% if I ran the registry clean might pay to do it again if I missed it
