When installing ANSYS 13.0 a message appears stating that there is a problem with the installation of one of the prerequisites - Microsoft Visual C++ Redistributable (x64).
|
The user had previously installed Microsoft Visual C++ 2005 Redistributable (x64) via SCCM using the vendor msi. This creates an Uninstall key in the Registry under HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall in upper case. The ANSYS installer checks for the Uninstall key in lower case and therefore doesn't recognise it and thinks it's not installed. Resolution: 1) Uninstall Microsoft Visual C++ 2005 Redistributable (x64) and allow the ANSYS installer to install it using the script vcredist.exe; this sets up the Uninstall key using lower case. or 2) Keep the current installation of Microsoft Visual C++ 2005 Redistributable (x64) and run the ANSYS installer using the option -noprereqs, ie: Use the dos cmd command to change to the directory containing the ANSYS installation files, or change to the drive letter for the ANSYS installation DVD by typing the drive letter, for example e:. Then type the command, setup.exe -noprereqs Note: The case-sensitivity of the ANSYS installer to the Registry Uninstall key will be resolved in ANSYS 14.0. |
