What Is Error Code 646?

The Windows error code 646 can occur under many circumstances. It is important to know what is causing this issue, how to fix it, and what you are going to do to ensure that it does not stop you again in the future. Most commonly, this error occurs when your computer is unable to install Windows updates. This may not be a common issue, but when you least expect it this problem can come up to bite you.

Generally speaking, error code 646 happens when the computer is started in safe mode. To fix this error there are several things you can do. One way of doing so is to start your PC in normal mode and then manually install the update. Of course, this is easier said than done. Some people don’t know what this means or how to even get started.

Another reason that error code 646 can happen is the use of the Windows firewall. This can prevent any updates from being installed, and in turn lead to this error message as well as several others. If you want to fix this issue you need to select the “firewall off” option on the control panel. After disabling this option you can again attempt to update your machine.

What about the Wups2.dll registry file? Again, this can cause issues such as the error code 646. To fix this common cause you need to delete the file from the registry by following a few manual commands. If this is not possible you should consider using a Windows registry cleaner. This will get rid of the file in no time at all without you having to do any work.

Not only does a registry cleaner fix all of the errors, but as an inherent bonus, it makes your PC run more efficiently. Basically, it speeds it up. I have yet to see a free registry cleaner, but it turns a difficult and time consuming job into a few minute fix.

If you are having an issue with error code 646 you are not alone. This is something that affects many people and their PC on a regular basis. Instead of dealing with the same error code, day after day, you need to fix it at once. As you can see by now, there are many causes of error code 646 as well as several ways to solve the problem. Don’t let the issue linger and cause additional trouble down the line.
