You need to reinstall SharePoint 2010, and you experience issues with the hot patches and English language packs installed in SharePoint.
Unloading:
1. Run the Configuration Wizard to detach the server from the service farm;
2. Uninstall SharePoint 2010 in Central Administration.
There are no uninstall patches (do not know where to uninstall) and language packs (lazy sickness).
New Installation:
1. Install SharePoint 2010 files;
2. Install patches (problems encountered here)
3. Install the language pack.
In the installation of the patch when prompted "not found in the system expected version", has already installed a hot patch, I thought reinstall can be, did not expect to appear this problem, a large part of the solution is to reinstall the server, this is too troublesome.
Online Solutions:
Run the following command with CMD (HotfixPackage.exe is the hot patch file name) to ignore the system check;
{HotfixPackage.exe} Package. BYPASS. DETECTION. Check=1
