Method 3: Add the SYSTEM user in the installer
Again, right-click the installer file and select Properties from the dropdown menu.
Navigate to the Security tab and press Edit.
Under Group or user names: press Add, and type in SYSTEM, with caps, and hit OK.
Make sure that the permissions are all set to Allow for the SYSTEM user. Close the dialog boxes by pressing OK on them. Try installing your software now, and it should work flawlessly.
At the end of the day, messed up permissions can cause a lot of headaches, and may mess with your ability to install software. All you need to do is to follow the steps in the aforementioned methods and you’ll be able to install your software without any problems whatsoever.
