I installed the Windows Vista with Service Pack 3 and I installed the Microsoft security essential to the system of the mines. Yesterday while working on critical Microsoft security update I have and tried to download and install, but I have to install error code: 0x8004FF07 and the system of mine left to install. I tried reinstalling, but I have the same error. Now I do not know how to solve this problem. Can anyone solve this problem and can solve the problem of mines.
I have same problem in the system of mines, and you have to delete some registry keys to solve this problem. To do this go to the start and after that make a hit in the run and type regedit and then click the OK button. Now, under the registry key to go to the following location:
HKEY_CLASSES_ROOT > Installer > UpgradeCodes > 1F69ACF0D1CF2B7418F292F0E05EC20B and here make right click on the 1F69ACF0D1CF2B7418F292F0E05EC20B and then delete it. After that now go to this location: HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Installer > UpgradeCodes > 1F69ACF0D1CF2B7418F292F0E05EC20B and then again delete the registry key 1F69ACF0D1CF2B7418F292F0E05EC20B. Now go through your theme.
When upgrading or installing the MSE sure you remove all third-party antivirus and anti-malware real-time and free to install the product by the manufacturer to buy. If you have not removed then remove the antivirus all third and after the use of some cleaning tools and restart the system. Now, once you reboot then try to install the update of MSEs. Hope this helps.
Hi thanks for answering and would appreciate your suggestions. I've gone through all suggestions, but does not help me solve mine problem. I deleted the registry key and after all I went to update, but give the same error. And after that I also removed the protection of the mines in real time, Norton and after that I tried to install the update, but also gives the same problem. Now I do not know how to solve this problem.
I would like to suggest you to uninstall the MSE and after that try to install the new again. To uninstall the MSE go to this steps: make strike on the start and after that hit it off on the run. Now beneath the run type cmd and then punch the ok button. Now beneath the command prompt type the following and after that knock enter after every command:
CD “C:\Program Files\Microsoft Security Essentials\Backup”
setup.exe /u
This uninstalls the MSE and after reboot and then install the MSE and then install the new updates.
