  1. If it doesn't work for u, try this:
    go to cmd (open as administrator)
    then type: sfc /scannow
    and wait untill 100%
    ^for me it worked^

  2. cmd's 3rd & 4th code dose not working?
    When i enter code *…….syswow64……. unregister OR regserver*

    It shows """The patch is not found"""

    Plz resolve it Bro

  3. I think you should specify that this fix is for windows 10. My problem is that my windows 7 installer isn't working and this is preventing me from installing windows 10.

  4. guys i dont know who the heck this guy is in real i am not a friend commenting a random person watching this i swear this worked for me no scamm try it and comment if it works thank you so much man it actually works i thought u were scamm

  5. Step 2 Check for Computer Software that are blocking the msiexec (Windows Installer) service. Here's my method. Sometimes Computer Programs especially Ransomware protection somehow can block the service and doesn't allow you to Uninstall Install or Update Programs. Solve the issue by Allowing the process by clicking remove in the blocked processes and putting it in the Allowed. Allowing the process might resolved the issue. If this method does not work. Then it's more likely that you will have to use the command prompt to solve the issue.
