Power Path 6.1 install on Windows Server 2008R2

So what are the implications of installing PP 6.1 without the hotfixes?  Does it fall back to using SHA1, or does it fail to work?  Background: KB2921916 is a hotfix you receive by request and only to install if affected by the issue in the article.  Trying to install it for us generates "This update is not applicable to your computer" The setupapi.dll referenced in the hotfix is newer on our machine than that referenced in the article. (Perhaps it was superseded by/included in a newer quality rollup?)
 
This puts us in a position of only being able to install PowerPath 6.1 with the NO_KBCHECK=1 option-- which may open up unknown cans of worms (especially if that causes breakage of some kind if SHA-2 support is required but present).

it sort of seems that perhaps PowerPath 6.1 installer should be checking something else (and/or I should before doing PP 6.1 install with the skip check option)-- like date of the above mentioned DLL and/or presence of SHA-2 support perhaps?

Hello Blueblade, I think it may be best to log a service request and we can engage PowerPath engineering to update on whether the installer needs updating. Please ensure you quote the EMC and MS KBs.

Regards, Michel.

Hi Michel, Blueblade - I checked with engineering and they are aware of this issue and looking into it. Will let you know if there is a resolution or they need more information.

Hi Blueblade,

PP engineering stated that installing PP 6.1 with 'NO_KBCHECK=1' option without the mentioned KBs or its superseded ones could result in a host crash / BSODs.

So KBs KB2921916 and KB3033929 must be installed prior PP 6.1.

Refer to this KB article from MS on what scenarios we will get "This update is not applicable to your computer" error

https://support.microsoft.com/en-in/help/3057448/-the-update-is-not-applicable-to-your-computer-error-when-you-install-windows-updates

Most likely KB 2921916 is superseded and the server is already running the newer version. You can check the file version e.g., \windows\system32\setupapi.dll from your host and what's listed in the KB2921916.

In this situation, you can safely go ahead and use 'NO_KBCHECK=1' option.

PP Engineering feels that it is user's responsibility to cross-verify and confirm that before using this option.

regards,

Evelyn

is that still mentioned in the PP 6.2 installation manual are these MS KB als required for PP6.2?

It is mentioned on page 16 of the PowerPath 6.2 Release notes

yes but it refer to PP 6.1

These hotfixes are required for PowerPath 6.1 and later. I will request the documentation be changed.

Thank you

Sam
