Ways To Fix Slbcsp.dll Errors When Trying To Install On Your PC

Slbcsp.dll is a file used by the Windows Installation protocol to help it place all the files and settings that various applications require onto your system. Unfortunately, this file and Sccbase.dll often cause problems with various installers on your PC, including the installation setup for HP Printer drivers. This tutorial is going to show you how to fix these errors…

What Is The Slbcsp.dll Error & What Causes It?

The slbcsp.dll error is caused by your computer being unable to read the file and settings that slbcsp.dll requires to run. In order to fix this, you need to be able to fix the various problems that are preventing the slbcsp.dll file from working. The most common causes of this error include the likes of registry errors, virus infections and general corrupt files.

The error that slbcsp.dll often shows is this:

“Issues stopping installation:

slbcsp.dll (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Defaults\Provider\Schlumberger)
This is a Cryptographic Service Provider manufactured by Microsoft.

sccbase.dll (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography|Defaults\Provider\Infineon)
This is a SICRYPT Base Smart Card CSP manufactured by Microsoft.

These registry keys do not exist and are required for installation to continue. Please ensure that the registry keys exist and click Retry to continue installation.”

How To Fix The Slbcsp.dll Errors On Your PC

Step 1 – Make Sure There Is Only 1 Copy Of Slbcsp.dll & Sccbase.dll

In the C:\Windows\System32 folder, there should only be one copy of slbcsp.dll and sccbase.dll. In order to ensure that this is not a problem, you should first browse to this folder on your system and make sure there is only one copy of each file. If there is any more than one copy of each, then you should make sure that you rename one of them to make it so that there’s only a single copy. Windows can often become confused if there are two copies of the file in the same folder of your PC.

  9. Now, right-click on an empty area on the right-pane of Registry Editor window, select New, and then click String Value.

  11. Now, right-click the string value, Image Path, click Modify, and in the box under Value data write C:\WINDOWS\system32\slbcsp.dll.
  12. Click OK.
  13. Next, select the Infineon SICRYPT Base Smart Card CSP key.
  14. Repeat the step 9 and 10.
