Unable to open registry key, access is denied.

Hello,

It looks like the error you’re facing is because of your not having permission to the subkey of the registry that is required to complete the installation. You have to take owner of the registry to complete the installation.

1. Start Registry Editor with administrative privilege. From Start menu, type “regedit” >> right-click on “regedit.exe” and select “Run as administrator”.
2. Browse for the subkey section from the left pane.
3. Right-click on the key >> select “Permissions…” >> “Advanced” button >> “Owner” tab.
4. Select built-in “Administrators” group >> click “Apply”.
5. Open “Permissions” tab.
6. Give your account for “Full Control” of the key.
7. Press Apply >> OK.

Now, run the installation.

Also, another technique can be used that will help you do every task with highest administrative privilege.

1. Start Command Prompt with administrative privilege. Right-click on “Command Prompt”, select “Run as administrator”.
2. Run the following command:
   net user administrator /active:yes
3. Logout of the current account.
4. You’ll see a new account with “Administrator” name. Login into it.
5. Run the installation.

After your task is complete, you can disable the account using this command:
net user administrator /active:no
