On Windows Server 2012 R2 (64-bit) this is almost always a missing VC++ runtime + Universal CRT (UCRT) issue. To fix the VCRUNTIME140.dll and api-ms-win-crt-*.dll errors (freshclam.exe / AV components), you only need to install two prerequisites:
Microsoft Visual C++ Redistributable (x64)
File: VC_redist.x64.exe (Visual C++ 2015–2022 runtime)
Universal C Runtime update for Server 2012 R2 (x64)
File: Windows8.1-KB2999226-x64.msu (KB2999226 – UCRT)
Microsoft Visual C++ Redistributable (x64)
File: VC_redist.x64.exe (Visual C++ 2015–2022 runtime)
Universal C Runtime update for Server 2012 R2 (x64)
File: Windows8.1-KB2999226-x64.msu (KB2999226 – UCRT)
- Recommended fix (quick steps):
- Run Windows8.1-KB2999226-x64.msu first
- Then run VC_redist.x64.exe
- Reboot the server
- Re-run the GetOverX Shield Server Edition installer (or run the update step again)
- After those two packages are installed, freshclam.exe should start normally and the antivirus components should complete setup successfully.
