I just bought the new anti virus 5. I have windows 7 under 64 bit. I try to install the file and im under administrator(admin) account and when its getting to the part of copying new files im getting this error: Error getting file security C:\Program Data\ESET\ESET NOD 32 Antivirus\updfiles\em003_32_l1.nup GetLastError : 5 I dont know what does it mean and why it happening all the time. I had before nod32 anti virus 4 no problems i removed it and wanted to install the new anti virus 5 version to use my new license codes but cant install it. Any ideas how to solve it ? Thanks.
