Hi hrmayer,
a. Do you remember making any recent changes to your computer?
This error is usually a failure to initialize a DLL correctly. This could be because the file is corrupted, missing, or possible has been added to with malicious code.
Try opening the command prompt as an administrator by following this step and run a System File Checker Scan(SFC) on your computer.
SFC tool scans system files and replaces incorrect versions of the system files by using the correct versions.
To run the System File Checker tool, follow these steps:
1. Click Start, and then type cmd in the Start Search box.
2. Right-click cmd in the Programs list, and then click Run as administrator. If you are prompted for an administrator password or confirmation, type your password or click Continue.
3. At the command prompt, the following line, and then press ENTER:
sfc /scannow

Note: If you are not able to perform this step in Normal mode, boot into the Safe Mode and perform this step.
Safe mode starts Windows with a limited set of files and drivers. Startup programs don't run in safe mode, and only the basic drivers needed to start Windows are installed.
Refer this link to boot into Safe Mode:
