Windows 7 can't install a program or an update.

own, I installed win 7. Since then, I am unable to install any software. I inserted the cd for my hp printer, but ot froze in the middle of the installation process, so I'm unable to print from it. I download the software of the printer on the net, but he also failed. I try to update windows security essentials, but after nearly 99%, an error is showing error network but wifi was working fine. I try to update to chrome, but it froze on 0%. also tried to install another anti virus - free panda anti virus, but he stopped too after completing nearly about 99%. I tried to run microsoft fixit to remove the error of installation and uninstallation, but she also showed an error. I am also unable to uninstall microsoft security databases.

Please help me!

Hi Apoorvlathey,

Thanks for the reply. I appreciate your efforts to solve this problem.

Have you tried to reset the Windows Update components and perform the boot as suggested by Andre Da Costa in the previous post?

1. reset the Windows Update components contains registry editing steps.

Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the the Microsoft Knowledge Base:

2. also defining the system in a clean boot state will help you identify if any of the applications third-party or startup items are causing the problem.
