Please help me!!! I have ever instlled NOD32 v4.0 to my laptop, use Windows Vista. I want to re-install NOD32. But after I uninstall (removed C:\ProgramFile\ESET and C:\ProgramData\ESET), run the Installer Cleanup and ESET Uninstaller, but I can not use NOD32. After I uninstalled, I re-installed NOD32 v4.0. Everything is normal. But it did not display the splash screen same as other times. So I must open by Start - Programs - ESET - NOD32... But it display a error window, "Failed to read firewall configuration". I press the OK button, the ESET NOD32 interface is display, but the date of updating is wrong. I press the F5 key to advance set up, the error window "Failed to read firewall configuration" was display again. Press OK, I see the advance setup windows. The system protection check box was disable. I check it, but after OK, it not change. I re-installed many times, so can not fix this error. I used the SysRescue Disk to scan, no threat have detected. Please let me know the way to fix this. Thank you very much.
