The expected version of the product was not found on the system
Today I have tried to install SP 1 for Arabic Language pack in environment which installed with SharePoint 2010 with SP 1 in one setup file (SlipStreamed) so when I run the setup I got the following error:
“The expected version of the product was not found on the system”
Fix:
So to fix this problem I have tried what is mentioned in the below article which suggested to run the setup from command prompt as following:
C:\serverlanguagepack2010sp1-kb2460056-x64-fullfile-ar-sa.exe PACKAGE.BYPASS.DETECTION.CHECK=1
