Hi,

I am trying to upgrade PowerShell version 2 to version 3 on Win7 x64 bit OS using update (KB2506143) but i won't be able to update it and when i checked system log file it shown an error:

Windows update "Update for Windows (KB2506143)" could not be installed because of error 2148204800 "No signature was present in the subject." (Command line: " "C:\Windows\SysWOW64\wusa.exe" "D:\Windows6.1-KB2506143-x64.msu"  ").

Also i tried to install update for PowerShell version 4 and it also failed to install.

Hi Gomesh,

I recommend you post this on Window client forum also, as this is exchange forum to discuss  exchange issue.

Thanks for understanding!

Best regards,
