I'm stuck while installation of FIM patches. Our current build is of 4.1.3419 and I'm trying to install the patch 4.1.3441.0 and getting error as "Forefront Identity Manager Service and Portal Setup Wizard ended prematurely because of an error." Even tried directly to install the patch 4.1.3451.0 but got the same error message.

Additional Query : Is there need to install all the patches or we can directly jump over to the 4.1.3

You have to check msi installer logs, it contains detailed description on what's failing.

Patches are cumulative.

Additional Query : Is there need to install all the patches or we can directly jump over to the 4.1.3634.0?

Any thought on this?

Patches are cumulative, you can install latest one.

MS says do not install FIM Patches if you have no need for them. FIM patches are not like OS Patches. They usually address specific issues raised by customers and whatever fix it was meant to address, it may not be applicable to you.  So, why did you want to install this Patch?

Well Nosh,

We are in a process to upgrade our DC from 2003 to 2012 R2, in leu of which we have a thought as suggested by MS to upgrade FIM to the build number 4.1.3634.0. If you have more information on AD upgrade in consideration with FIM 2010 R2 aspects, it would really be helpful.

Manuj,

I don't have any suggestions on AD Upgrade, but I am not sure how this is related to FIM

Have you got Sharepoint Administration service running during patch? Is user running patch a member of farm administrators?

Try msiexec /p FIMService_x64_KBXXXXXXX.msp /l*v c:\temp\fimpatchlog.txt

I've always been lead to believe otherwise, is this something they've announced publicly? I think the reason this surprises me is that the hotfix release pages often state:

A supported update is available from Microsoft Support. We recommend that all customers apply this update to their production systems.

FIM-EN,

Here is the official page for this patch. https://support.microsoft.com/en-us/kb/2814853?wa=wsignin1.0

I am not seeing the verbiage you mention.  If you are referring to Windows and security patches, then that is a different story. To the best of my knowledge, the recommendation has been to exclude FIM from "automatically updates".

On the link you sent, the first line below "Update Information", below "Introduction" is the line I quoted. 

I agree completely in that I wouldn't jump in and perform the update on release day, I do tend to update after a couple of months assuming no talk of problems. But judging by that line it seems the recommendation is to apply this hotfix regardless of issues. 

I probably would upgrade too, but since there are issues with it, I question the need.

4.1.3634.0 provides 2012 R2 for PCNS and ADMA so updating to that should be all you need to do from a FIM point of view.
