I am trying to do a silent install by running:

clamwin-0.93-setup.exe /VERYSILENT /SUPPRESSMSGBOXES /NORESTART

This is on a system that already has clamwin 0.92.

However, when I do this, I get a message box with a title of "ClamWin.exe - Entry Point Not Found" saying

"The procedure entry point cw_normalizepath could not be located in the dynamic link library libclamav.dll"

It appears that the normal silent install option is broken for the 0.93 release. I can run the installer normally by double clicking on it.

the problem is that with /SUPPRESSMSGBOXES the setup does not close clamtray.exe (because there is a messagebox asking it). Loaded clamtray.exe prevents libclamav.dll from being updated and hence you receive this error. It should be fine after a reboot though.

Alternatively you may use pskill.exe to kill clamtray.exe before running the silent setup.

I don't see ClamTray.exe running. I also run WClose prior to running the installation which seems to at least kill ClamTray.

I also tried running "%PROGRAMFILES%\ClamWin\unins000.exe" /VERYSILENT /SUPPRESSMSGBOXES /NORESTART /NOCANCEL prior to the installation - it seems the dll is tied in somewhere else, because now I get the same error when I run a manual installation.

try to reboot and then if poblem persists do a search for libclamav.dll on your machine
