The 25002 error is a typical problem that rears its head when you attempt to install / uninstall Norton or Alcohol on your computer. This error mostly occurs when your PC does not have the appropriate permissions, or drivers to carry out the operations you are asking of it.
This error is mainly driven by the way in which Windows can not process files and settings needed to run the system properly. The usual format of this error will show itself as:
- "Error 25002: Failed to load navinst.dll."
The causes of this problem can be attributed to the way in which your computer can not read the files or settings required for the installation / un-installation to take place. Typical examples of this problem will be when your user account does not have the correct permissions to run the file, or when you are experiencing file corruption issues with the "registry" of your system.
How To Fix The 25002 Error
Fixing the 25002 error is simple. The first step is to ensure you have the correct permissions on your system. Most software can only be installed and uninstalled by the user account that has the required rights to do so, eg the administrator. If you're not logged in as the administrative user, log out and then log in again with the correct user account that has permission to install in your system.
The next step is to check if your Navinst95.dll or Navinstnt.dll file is damaged or corrupted in any way. If so, you have to repair any of the problems which are causing the errors by clicking "Start" and then selecting "Search". After this you have to locate Navins95.dll and Navinst.dll and rename them both as "navinst.dll". The third step is to fix any corrupted and unreliable settings inside your computer that are stored within the "registry" data house. These stored settings can establish how your computer is capable of installing a program correctly onto the hard drive. These registry errors can be resolved by clicking "Start" and then selecting "Run". When a box shows up, type "regedit" and then press OK. Now, locate the following registry key when the Registry Editor window appears:
HKEY_LOCAL_MACHINE System CurrentControlSet Control File System .
The next thing to do is to double-click NtfsDisable8Dot3NameCreation in the right pane and then change the data in the Value data field from 1 to0. After, exit RegEdit and restart your PC. After that, install Symantec AntiVirus Corporate Edition client on your hard drive. When installation process is finished, change the value of NtfsDisable8Dot3NameCreation file back to 1.
The final step for resolving 25002 errors is to use a registry cleaner device. The registry is a major reasons for the 25002 error appearing, as it is the central database which stores all the vital settings and options that is required by Windows each time you use a program like Norton or Alcohol. It is responsible for storing your recent emails and files, including desktop wallpapers and the like. If you want to completely fix the errors appearing in your computer, you should clean through the registry by using a registry cleaner. There are quite a few programs available, but not all are equally effective. Therefore, only download one that has been recommended by professionals.
