I was trying update my ESET NOD32 installation from v9.0.377.0 to v9.0.381.0 using offline installer. My operating system is Windows 7 SP1 64-bit. The installation failed with error code 1603.

I ran the recommended Specialized Cleaner but it didn't find anything.

I then tried to uninstall the previous version from control panel and found that the uninstallation was password protected, although I don't remember locking my settings with any password. I confirmed it by going to Advanced Settings. Password prtection was turned off there.

Then I booted into safe mode and uninstalled the previous version using ESET Uninstaller following the instruction here. (Uninstaller log attached)

I restarted PC and tried to install the newer version again but got the same error.

I then tried a few things -

  • Turned of Windows Firewall temporarily.
  • Ran ESETSirefefCleaner as instructed here.
  • Tried the live installer.
  • Tried to install v8 (which also failed with another error 2803).

But no luck so far.

What can I do now?

Well, my issue was automatically resolved after installing the latest Windows updates. I was able to install the latest version of ESET NOD32 Antivirus without any problem afterwards.
