QA00000061233_CST Studio Suite Installation Failure CSTInfo_AMD64.dll - Error 1904 or 1905
Question:
What to do if the installation of CST Studio Suite fails because of the CSTInfo_AMD64.dll - Error 1904 or 1905?
Answer:
The installation of CST STUDIO SUITE may fail with Error 1904 or 1905 stating that:
<CST installation>\AMD64\CSTInfo_AMD64.dll failed to (un)register
This can occur when the Microsoft Visual C++ 2015 redistributables are skipped during installation (e.g., due to a corrupted registry) and thus the required DLLs are missing.
The solution is to manually install the latest Microsoft Visual C++ 2015 redistributables. Please check for the the latest supported Visual C++ downloads.
