Yes, the exact message is:
"A problem is preventing Windows from accurately checking the license for this computer. Error code: 0x80090019."
Review of this site came up with what might be a repair -- http://www.geekstogo...een-t40187.html
In my situation I have two software files -- software from the hive that has all the keys, etc and worked before I reloaded Windows (thinking that process would "heal without harm" the error message that I had just received from windows). And I have software from the re-installed version -- which is basically missing all the software. I've been on the phone with MS to get to this point -- a computer with two XP installations (WINDOWS -- the old installation) and (WINNEW) the blank installation. The WINDOWS installation can be made to get past the error message above by using the software file that was created when Windows was repaired. When this repair occurred, Windows evidently does harm -- it doesn't save the restore points from a previous install, rather overwrites them, thus necessitating reinstalling all the software again. My backup (yes, I had backup) was on a separate drive, which then had a mechanical failure (it goes click-bing repeatedly and the OS doesn't recognize it). So, I am in a world of hurt.
As is the case of this message:
1. I cannot boot into safe mode when using the desired software file.
2. I desire the software file under the belief that using this will avoid re-installation of all the software again, but will require some re-registration (likely of Windows). My copy of Windows is a store bought, fully packaged XP Pro.
3. The first step of the suggested solution was to go into registry and change some values. I could do this with the working software file, then replace to the desire software file -- but without knowing that the change affects only the other files in the hive, it could be a useless exercise. If it requires changing the desired software file, how do I edit it when Windows won't come up to permit access through regedit?
4. I do have access to norton system works and have done byte level editing in the DOS/95 era, but not in XP.
Thank-you for your interest in this issue.
