You just need to boot from this disc and run a repair installation, and give it your new valid key code.  This should get you fixed up.\n\n~Kyle

Here is your fix:\n\nYou MUST have an OEM Win XP CD.\n\n1. Boot up with the WinXP CD and at the Setup Screen press the Enter Key.\n  \n2. You will be taken to the Windows XP Licensing Agreement. Press F8 to proceed.\n\n3. The next screen gives you the option to do a fresh (clean) install or to repair\n     the selected Windows XP installation. To run a Repair Install press "R".\n\n***CAUTION*** if you do not see the option to repair the selected Windows XP\ninstallation DO NOT choose the option to continue installing a fresh copy without\nrepairing as that will overwrite your data and cause unrecoverable data loss.\n\n4. If you originally installed XP with Service Pack 1 and later installed Service Pack     2,  you will need to re-install Service Pack 2.\n\n5. If you have any Microsoft Office products installed,  you will need to re-activate\n    with the Product Key code. Contacting Microsoft may be required.

I am going to believe that you have a legit copy as you say.\n\nwhen windows updates there list of bad serials they sometimes hit good ones, it is not very often but it does happen.\n\n\nthere are also programs that can generate random keys, if you key was used by pirates they would block your serial.\n\nGive Microsoft a call and they will help you out. You will need your serial number and info on where you got your copy. \n\nThis happened to a group of PCs at my high school. (some kids lifted the serial)\n\nmore on what you can do:\n"Complimentary offer: Microsoft will make a complimentary copy of Windows XP available to customers who have been sold counterfeit Windows. Customers will be required to submit a proof of purchase, the counterfeit CD, and a counterfeit report with details of their purchase. Only high-quality counterfeit Windows will qualify for the complimentary offer."\n\nmake a backup of you cd and key and then send in the orignals with proof of purcase.\n\nall the info you need is on:\nhttp://www.microsoft.com/genuine/downloads/FAQ.aspx?displaylang=en#Question5Label

go to: my computer, right click it, go to properties, go to hardware / device manager, and look for IRDA. it is possible that xp installed it by itself.

Call customer support and let them know your trouble. They will usually give you help on it by either giving you a seperate code after you uninstall and install the software again, or if by any chance you did not validate the product when you first installed it, you may do so online, or just call them for a key code that your program may validate the software as being genuine ms office xp pro.

yo boobooed\nthe easiest fix, is to boot from your windows xp cd, and when given options, the first time it asks, say intstall, the secon time say repair, it will do a non-destructive install and replace any bad or missing files or associations.\nYou could check in the recycle bin and if it is in there, restore it

Some software providers may still have them for sale.\nBut almosy everyone has been selling XP for years.\nWhat happened to yours?\nWhy can't you upgrade to XP?\nIf yours is damaged, you may be able to get a replacement from MS. If it's lost, make a backup copy next time.

Do yourself a favor and buy a licensed copy of XP.  \n\nAnd when you get it, reinstall Windows doing a "clean" install.  You'll be surprised how much of a difference that will make.  Look into making backups onto DVD or a second hard drive as well.  Once you do a clean install and reinstall all the apps you use the most, make a backup right away.  That way you'll have a quick restore disc you can go back to anytime you have problems down the road.

Most people forget about this with XP but the best and eaisest thing to do is do a system restore to a point before you messed with it. It will work and you wont lose anything.

If you only installed an additional hard drive that should have had no bearing on the XP Install Key. \nDid you purchase XP from a retailer or on-line?\nIs this computer a used computer you got from someone else or purchased new with this operating system installed?\n\nIn the new patches for XP there is a new key check process.\n\nIf you purchased the CD On-line, you most likely got scammed and it's not a legal copy.\nIf you purchased from a retailer I hope you saved your receipt as I would bring it back for an exchange if possible. (not likely)\nIf you had it preinstalled on the computer and purchased the computer new, you need to contact the tech support of the computer manufacturer to clear it up.\nIf you purchased the computer used, pre-installed you do not have a legal copy of XP.  \nHope this helps.

If XP doesn't work I would try Win98. If you really want 95, look at ebay I am sure you can get a copy for $5 or so.\nhttp://cgi.ebay.com/1-DAY-ONLY-Full-Inst-Windows-95-Win-OS-operating-system_W0QQitemZ7233443216QQcategoryZ41883QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Windows XP is a protected operating system which means it usually can't be copied.  If it could be copied, people all over the world would be giving copies to their friends and Microsoft wouldn't be making any money :-)  Having said that, there's a couple of things you can try.\n\nHave you tried doing a custom startup to see if you can "uncorrupt" your system?  At startup,  press the F8 key repeatedly and it will take you to an Advanced Options Menu.  One of the choices will be Last Known Good Configuration.  Use the up/down arrows to highlight it and press enter.  It will try to boot XP using the last hardware configuration that actually worked. If this fails you can again access the Advanced Options Menu. This time highlight Safe Mode and see if you can use a System Restore Point that will return your machine to a time in the past before the corruption occurred. (Click start > help and support > system restore > restore my computer to an earlier time > next > follow prompts.) I'd scroll throught the calendar and pick the earliest restore point you see (maybe in a previous month.)  And if this doesn't help, you can try looking through your system files and recovery disk for XP setup.exe.\n\nIf you can access safe mode, try to run a full system search for something called an i386 file. This file (if it's on your computer hard drive) will be at least 200MB, probably closer to 500MB and is an exact copy of the Windows XP operating system.  If you have it, you can use it to reinstall XP. If it's on your hard drive you'd have to copy it to a separate disk because any formatting of the hard drive erases everything, including the i386. So I'd try an advanced search.\nClick start > search > all files and folders.\nType in i386 in the all or part of file name box.\nLook In: My Computer (using drop down arrow.)\nClick on More Advanced Options.\nCheck mark Search System Folders, Hidden Files and Folders and Subfolders. Uncheck the last 2 items.\nRun the search. You might find some i386 files that are 50MB or so but the one you need will be at least a couple hundred MB.  This article gives a bit more info about the i386 file:\n\nhttp://ask-leo.com/so_just_what_is_the_i386_directory_anyway.html\n\nFinally, if you can't find the i386 on the hard drive, I'd put your recovery CD in the reader and look for the i386 on it.  If you find it, the i386 should contain a setup.exe file that should get you going again, or you might find an XP setup.exe file all by itself. But no guarantees.  Hope this helps and good luck.\n\nplrr
