问题
I rebuilt a laptop and in the process installed VS2017 which includes an install of C++ 2017 Redistributable(x64) - 14.10.24728
I have tried installing other apps that use C++ Redist 14 and they fail with the error message:
"Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel. "
The following components failed to install: - Visual C++ "14" Runtime Libraries (x64)
I've tried installing C++ Redist (x64) - 14.0.23026 but get error message "Another version of this product is already installed etc."
Is there any way to resolve this without uninstalling VS2017 and reverting to VS2015?
PS: can someone with sufficient rights add 'visual-studio 2017' to tags list?
回答1:
The VC++ 2017 redistributables REPLACE the VC++ redistributables. See here for more details on how this can be checked programatically.
If you just need a program to use the VC++ 2015 redistributables, and the VC_++ 2017 redistributables are installed, given that it's an upgrade, the program requiring the 2015 version should work with the 2017 version.
