KB2465367 – a repeat of the KB971090 roll-out problems?

Today Microsoft released KB2465367, a Microsoft Visual C++ 2005 tools update. See:

For those of you that remember the problems that KB971090 caused to developers, I suggest you look at this patch carefully before rolling this out, to see if it affects your particular development environment. To remind you of this, please go and read my blog article about KB971090 at:


NOTE: I’ve confirmed that the exact same technique used to update the VC libraries and DLLs in KB971090 are used in KB2465367 also. That is, the manifest version of your app will be increased to 8.0.50727.5592 (from 8.0.50727.762 which was the original SP1, or 8.0.50727.4053 which was the July 2009 security update). This security update contains the new MFC fixes, as well as the original ATL fixes from July 2009.

    Oh yeah. Same problem again, but now it’s worse.

    I am getting a dependency on 8.0.50727.5592 and a failure to load it despite the fact that I have it in SxS. I get something rather obscure.

    ERROR: Two assemblies have the same assembly name with different version. Assembly 1: C:\Windows\WinSxS\manifests\x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.5592_none_d09196c24426e2d4.manifest. Assembly 2: INFO: Manifest found at C:\Windows\WinSxS\manifests\x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.5592_none_d09196c24426e2d4.manifest..
    ERROR: Activation Context generation failed.
    End Activation Context Generation.

    Maybe you have a clue why this happens?

    If I try to force 8.0.50727.762 as you described, some other dependency still brings in the new CRT. It’s a mess.

    If you care helping an open-source project, we’re having a thread on this here: http://dotnetinstaller.codeplex.com/discussions/255515. I could really use some help from professionals :)
