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

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.
