In this post we will discuss about an error which usually comes while running the setup.exe for Microsoft SharePoint server.
Also you can check out my previous posts on:
Setup is unable to proceed due to the following error(s):
A system restart from a previous installation or update is pending. Restart your computer and run setup to continue.
To solve this issue, you have to delete the following registry key.
To delete the FileRenameOperations registry key
Open a registry editor, such as Regedit.exe or Regedt32.exe.
Navigate to HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\
In the right navigation pane, right-click the PendingFileRenameOperations key and select Delete.
Close Registry Editor
This solution is applicable for both sharepoint 2010 and 2013 versions.
