Hi

We have 34 customers and we configured a separate farm for each customer as reflecting to Production environment. Our production servers recently got patched with SharePoint 2013 July CU and we are also refreshing our LAB servers with the same patch.

I tried to install the July CU 2015 patch on all 34 customers. 17 farms are successfully updated and 17 farms are failed with error message "Expected version not found on the system" even same package we installed in all 34 farms. And we installed these patches from Microsoft MSDN site only. Below steps are I performed.

1: Run the exe directly form the downloaded folder with farm admin & System admin account. Got the above failures message 

2: Later run the exe from windows power shell as well share point power shell  with farm admin & System admin account.

         ps c:\> ubersrv2013-kb305937-fullfile-x64-glb.exe package.bypass.detection.check=1

But have the same message.

3:While I checked in CA>>System upgrade status>> APP, FE1 and FE2 are having the few language patches are missing/required. For this I followed these below steps

Tried running the Get-SPProduct local, in the servers where we had the issue. But still the issue persists.

Tried running the command (psconfig.exe -cmd installcheck noinstallcheck) and it is successful.

Now tried installing the July CU again, but again it was throwing with the same error.

Removed the server FE01 from the server farm.

Tried installing the July CU again, this time also there was no difference.

Cleared the configuration cache and tried again, still no difference.

 

I tried all the possibilities  with trail and error. But failed.

Most of  the patches are missed relating to the language packs. Earlier we have installed July 2014 CU. Now we are trying to install July 2015 CU.

Please help me. Even If I tried to upgrade  to August 2015 CU, I got the same result.

yes language packs could be an issue.. Run an ROI scan on all servers to check if there are any chained products missing in SP

2. Install the Language packs
