i'am installing Nintex Forms 2013 an hour earlier then when it comes on upgrading nintexlivecore.wsp until now its not done. why is this happening?
This might be due to a task lock, such as the Live Relay Service. When you were updating the solution, the Nintex Live Relay Service may not have stopped. Before you update, stop the Nintex Live Relay Service and perform the upgrade again.
I've seen this before myself. In my case the clients SharePoint farm was awaiting a timer service to deploy the WSP to another SharePoint server that actually didn't exist. In the end we had to rely on deploying the WSP manually through PowerShell instead of the installer.
