During the installation of the Defender Desktop Login software, the error “An error occurred during the installation of assembly ‘Microsoft.VC90.CRT, version=”9.0.30729.6161”,publicKeyToken=”1fc8b3b9a1e18e3b”,ProcessorArchitecture=”amd64”,type=”win32”.” Is displayed.
This error can occur if the prerequisites are not installed before installing the Defender Desktop Login software.
It appears that the error is caused as our required redistributables are not installed.
The required C++ redistributables can be located within the following directory of the Defender installer downloaded ZIP package: \Redistributables\Microsoft Visual C++ 2008 R2 SP1\vcredist_x64 SP1.exe
After installing the above the installer Desktop Login should install without issues.
