I\'m trying to install SAP Crystal Reports runtime engine for .NET framework on a fresh new Microsoft Windows Server 2012 R2 x64 virtual machine. The installation stops with thi
SAP Crystal Reports Runtime 13.0.21 and above requires:
Windows 7 with Service Pack 1 or above.
Microsoft Windows Update KB2999226 (require Service Pack 1)
Microsoft Visual C++ 2015 Redistributable (require Service Pack 1)
Install all of the dependencies and you will get rid of the "failed to register .dll".
