Bypassing windows update error 0x80096002

Question

I am getting this error when I try to install some .msu files (WMF 3 if it matters).

Now, the error is saying that the certificate is invalid. However, I looked at the certificate (if anyone is curious, here is the public key for the cert:

30 82 01 0a 02 82 01 01 00 ee 5b be 7d 11 24 e3 86 06 e0 66 ff 48 b5 17 bd 02 e4 b4 0c 32 f0 72 3e 7d 2e 87 d7 4e a1 b1 a7 43 2f f7 65 9e 31 e1 32 31 45 ae d7 c1 24 84 21 d7 2e b5 84 7e fa 35 d3 53 1c d7 b6 51 1e 4f ce 66 b9 eb b7 0c 02 fd 29 5c ad a8 87 f6 ca 22 b4 d5 bf 08 75 f5 8a 70 8f 63 d7 ef 8a 1e e9 8f 43 24 64 5a d3 87 7d 90 6d 3b ac 76 cd 57 36 7d e8 bc 10 56 ac 98 f0 89 5d 2e 64 c6 af 26 09 5e 1e 63 15 f1 3d bf 16 8f 99 88 02 c3 30 b7 c1 0b 60 1f 0f 72 cc d6 b7 a8 35 12 86 9b a1 0b 0a e6 93 5b 8e fa 54 9c c1 f3 19 5f 42 8d 12 9f 1d 3f 90 b7 27 13 83 19 32 82 1d f3 d9 87 d4 21 b2 3c a2 b6 07 4f d7 24 aa ee 8d f5 b3 d9 fa f9 39 4f a7 e9 f2 af 59 52 f4 dc 41 9b 2f 11 70 63 dd ea de aa f1 6d 21 04 10 53 33 bb b2 4f c5 e1 53 b2 41 65 47 6e 37 f6 bc e9 9b 16 41 91 6b 2e 5b 30 c3 02 03 01 00 01

)

Now, I have already tried installing the certificate, and it said it went though, but it still gives me this error.

So what I am looking for is a way to:

1. Figure out what is causing this error, and actually fix it
2. Find some way of installing the .msu without it checking for a signature.

As an aside, the rest of the time, my windows update appears to work fine.

Edit: I attempted to install the update manually (based on this KB article) but I got stuck at the pkgmgr line. It runs without errors, but also without doing anything.

Edit 2: Thanks to Oliver Salzburg, I have the following additional information:

Solution

The problem simply put is that windows 8 already comes with powershell V3. Trying to install int again causes problems as the files are already there, and similar issues.

have you tried downloading the problem update and installing it manually?

[soandos]

@Moab I have the .msu files in my downloads folder, and have been running them from there. Not sure how else to do it to be honest.

I have never used wusa to install an update manually, usually I download the update and is a self installing executable.

have you tried restoring to an older point in windows? Or repairing windows from a Bootable disc?
