Hi Guys, I have been trying to install NOD32 (not SS)V4 on my PC for testing. I had 3.0.684 (not SS) installed, which I tried to install over the top of. The installation hang on removing drivers. I rebooted and tried again - same problem. I uninstalled V3, tried to install V4 and now I get "The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2753" In event viewer, I get the same message with the extra "arguments are: eplgOutlook.dll I've tried rebooting and downloading the package again - same problem. Looks like it may be a problem installing the outlook module? This is on Vista Business SP1 and office 2007 Any Ideas?
