Hi,  
strange because when you are an Admin on your system, the FMS Data Manager installs the VC distribution packages during the setup.

You can try to install both packages manually:  
[Microsoft Visual C++ 2015-2022 Redistributable (x86)](https://aka.ms/vc14/vc_redist.x86.exe)  
[Microsoft Visual C++ 2015-2022 Redistributable (x64)](https://aka.ms/vc14/vc_redist.x64.exe)

After the installation, reboot your PC and try to start the FMS Data Manager again.

Cheers,  
Richard
