To check if Visual C++ redistributables are installed, open Add and Remove Programs and look for the Microsoft Visual C++ Redistributable. If installed, you see "Microsoft Visual C++ 2015-2019 Redistributable (x64) - 14.22. 27821".
Open Add and Remove Programs and look for Microsoft Visual C++ Redistributable. The installed versions will be listed there. This screenshot is from Windows 10.
The Microsoft Visual C++ 2008 SP1 Redistributable Package (x64) installs runtime components of Visual C++ Libraries required to run 64-bit applications developed with Visual C++ 2008 SP1 on a computer that does not have Visual C++ 2008 SP1 installed.
I don't think any of those solution can help when your using different OS ! For ex, MsiQueryProductState will always returned -1 using Vista VC8.0
while -1 for VC8.0/8.0 SP1/9.0 with Windows 7 ! So the GUID solution that microsoft provided, doesn't work in all cases
so i guess i'm forced to stuck with the %windir%\winsxs approach and search for
- x86_Microsoft.VC80.CRT*
- x86_Microsoft.VC90.CRT*
For those who are looking for all GUIDs, Here is a list i created:

Quick and dirty:
if (LoadLibrary(L"msvcrt80.dll")!=NULL)
{
// it is installed
}
