How to fix CRYPT32.dll missing or not found error in Windows?

Issue: Hello. I ran into a problem on my Windows 10 recently. I booted it up as normal and then attempted to boot Skype, which resulted in an error saying, “The program can't start because CRYPT32.dll is missing from your computer. Try reinstalling the program to fix this problem.” How do I fix this?

Solved Answer

Dynamic Link Libraries, or DLL files, are essential components in the Windows operating system, acting as shared libraries of procedures and functions that multiple programs can use simultaneously. This shared use allows for an efficient and streamlined operating experience, making DLL files indispensable to Windows OS.

DLL files, while crucial, can sometimes lead to system errors. An example of such an error is the CRYPT32.dll missing or not found error. The file in question, Crypt32.dll, is a module integral to both Windows and Windows Server operating systems. It's worth noting that there are different versions of it, each providing different capabilities based on the version of the operating system installed on your computer.

The CRYPT32.dll missing or not found error can occur for various reasons. You might experience this error because the Crypt32.dll file has been accidentally deleted, is corrupted, or has not been properly registered within the Windows registry. Malware or viruses might also be a contributing factor, as these malicious programs can damage or delete DLL files, causing subsequent errors.

To fix the CRYPT32.dll missing or not found error, various steps can be taken. You might need to reinstall the specific program associated with the DLL, recover the deleted file from the recycle bin, or even restore your system to a previous state before the error occurred. Updating your Windows operating system or the drivers of your hardware components may also be necessary to rectify the error, ensuring that the correct and most recent version of Crypt32.dll is being utilized.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
