When 64-bit version of AmiBroker is installed, the setup program checks in the system registry if required runtime libraries are present, and if not – then it downloads and installs proper runtimes from Microsoft website. However – it may sometimes happen that the information in the system registry indicates that the required runtimes are installed, while in fact they are missing or incomplete. In such situations we may see the following error displayed when launching AmiBroker:

To fix the problem we need to install Microsoft C++ runtime libraries vcredist_x64.exe manually. Correct x64 VC2005 runtime required by 64-bit version has the version number 8.0.50727.6195
It can be downloaded and installed from:
