RPCRT4.dll and WS2_32.dlls are missing

Hi Stuart,

I would like to inform you that most rpcrt4.dll and WS2_32.dll errors are related to missing or corrupt rpcrt4.dll and WS2_32.dll files. Because these are external files, it presents a great opportunity for something undesirable to occur.

Improperly shutting down your PC or getting a virus infection could corrupt the rpcrt4.dll, which could lead to DLL errors. When your rpcrt4.dll file becomes corrupt, it cannot be loaded properly and will present an error message.

I suggest you to follow the methods below and check if it helps.

Method 1: Install any available Windows updates. These will replace or update some of the hundreds of Microsoft distributed DLL files on your computer. The rpcrt4.dll and ws2_32.dll files could be included in one of those updates.

Follow the steps below.

1. Click on search bar, type Windows Update.

2. Select Check for Update.

3. Download and Install the latest Windows Updates.

Method 2: I suggest you to run Microsoft safety scanner and check.

To perform Microsoft Safety Scanner please visit the below link:

Note: The Microsoft Safety Scanner is a free downloadable security tool that provides on-demand scanning and helps remove viruses, spyware, and other malicious software. It works with your existing antivirus software.

Disclaimer: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.

Also I suggest you to disable anti-virus program, if installed on your computer and check.

Hope it helps. Revert to us with the results, will be happy to assist you.

Thank you.

 

RPCRT4.dll and WS2_32.dlls are missing

Hi,

Sorry for the delay in response.

I suggest you to Run the System File Checker tool (SFC.exe) and check if it helps.

System File Checker is a utility in Microsoft Windows that allows users to scan for file corruption and restore Windows system files such as rpcrt4.dll and WS2_32.dll. If System File Checker finds a problem with rpcrt4.dll
or other critical system file, it will attempt to replace the problematic files from DLL Cache (%WinDir%\System32\Dllcache\).

Follow these steps to run the command and check if it helps.

1. Press Windows key + X on the keyboard.

2. Click on Command prompt (Admin).

3. Type sfc /scannow and hit Enter.

Note: While performing SFC Scan I would recommend you to make sure that there are no applications or programs running on the back ground.

If the issue still persists, I suggest you to
restore from a system restore point:

This option takes your PC back to an earlier point in time, called a system restore point. Restore points are generated when you install a new app, driver, or Windows update, and when you create a restore point manually. Restoring
won’t affect your personal files, but it will remove apps, drivers, and updates installed after the restore point was made.

1. Right-click (or press and hold) the Start button, and then select
Control Panel.

2. Search Control Panel for Recovery.

3. Select Recovery > Open System Restore >
Next.

4. Choose the restore point related to the problematic app, driver, or update, and then select
Next > Finish.

Note:

If you’re not seeing any restore points, it might be because system protection isn’t turned on. To check, go to the Control Panel, search for Recovery, and then select Recovery > Configure System Restore > Configure and make sure Turn on system protection is
selected.

Hope it helps. Revert to us with the results, will be glad to assist you.

Thank you.

 

RPCRT4.dll and WS2_32.dlls are missing

Thank you Mohan,

There were no new updates avail for Windows 10.

At first I had trouble running the Microsoft safety scanner. After downloading the software I received a message "this program cannot run on this PC" or something to that effect (I forgot to write it down). Maybe it had something to do with my inability to
disable McAfee anti-virus program? After I restarted, I tried again and it downloaded and ran. I then performed a full scan and, after many hours, there were no viruses or malware detected. I guess that's good but do you have any other suggestions about
how to replace the missing or corrupt rpcrt4 and ws2_32 dlls.

Thank,

Stuart
