Trying to push out a piece of software using Patch Manger via WSUS and it gets installed on a few, but not most. I also tried to have the software install via Windows Update and it also fails. The install error it gives me is as follows:
Install failed. Fatal error during installation HRESULT: 0x80070643.
If i go on the client and go to the UpdateServicesPackages folder on my wsus server, and install from there, it works just fine. If i go to the SoftwareDistribution folder on the client, and try to install it, it errors out. After looking into the issue more, i have found out the issue lies when it downloads the files from wsus to the client. It doesn't download the entire contents of three .cab files, and it cannot figure out why. On the wsus server the file sizes of those three files are the following:
file2.cab = 62,127KB
file3.cab = 121,895KB
file5.cab = 181,168KB
these three file size replicate the original files from our software file server. However when WSUS downloads the files to the client, the file sizes don't match up
file2.cab = 62,119KB
file3.cab = 111,449KB
file5.cab = 181,158KB
And this software needs to be installed on 100+ machines, so going to each one is not practical. I can't figure out why it got installed on a few, but not all of them. And it's happening in multiple labs, where it might get installed on a few and then the rest it won't install.
I have been working on this for a few weeks, so any help would be much appreciated.
