My IMF was playing up, and it was thought that v1 was still installed as well as v2 (obviously installed with Exchange 2003 SP2). In add/remove programs IMF was listed so I uninstalled that with the intention of getting it working again. Now I realise that it was IMF v2, part of SP2, that I uninstalled.
Please can someone advise me how I can reinstall IMF v2? I've tried reinstalling SP2 but no joy - if I leave the "contentfilterversion" key in the registry it warns me I still have v1 installed. If I remove it, setup proceeds with the 'update' attribute, and I get a general installation error preventing me from installing SP2 further.
The error in the install log is:
***ERRORLOG EVENT*** : ISetupComponent::Pre/Post/Install() exception caught in ISetupManager::RunInstallPhaseAndCheckResults()
