Puremessage reinstall fails with COM error

Awalsh

Hi,

I've been tasked with fixing a Puremessage install on a Windows Small Business 2008 Server, it appears that after a recent security breach an attacker managed to uninstall both the main Sophos Anti-Virus suite and the Puremessage software (basically by deleting their folders in C:\Program Files, or at least that is how it seems).

Reinstalling Sophos Anti-Virus worked perfectly first time and is now up and running again. When attempting to install Puremessage for Exchange on this server, shortly after the installation startup begins (during the InstallShield setup part) I receive the following message:

"Setup encountered an error while gathering system information. Error Details: rk.Open(0x80000002, SOFTWARE\Sophos\MMEx\ZEUS, KEY_READ), dwError=2"

Where ZEUS is the hostname of the server.

The uninstaller is not available in Add/Remove programmes and I cannot find the above registry key either (or even \SOFTWARE\Sophos).

Has anyone come across something like this before? I am trying to avoid reinstalling everything on this server after the security breach, where possible.

Thanks,

Andrew

    I have had this issue before, and when I called into technical support, they told me to remove these registry keys.

    HKEY_CLASSES_ROOT\Installer\Features\2A47A649E29DEC043B5C6C71E46C82D7

    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Un-install\{946A74A2-D92E-40CE-B3C5-C6174EC6287D}
    HKCR\Installer\Products\2A47A649E29DEC043B5C6C71E46C82D7
    HKLM\Software\Classes\Products\2A47A649E29DEC043B5C6C71E46C82D

    It worked for me. Use at your own descretion and be sure to back up your reg keys before making any changes.
