First run error after installation

[Lycal]

Hi,

I've just purchased and installed the program, following the installation instructions.

When either starting the standalone program, or running FS2020 I get a lot of error messages saying:

"Error: LoadLibrary failed to load <filename>. GetLastError: 126"

Examples of filenames are:

iop_c.dll
iop_d.dll
iop_com.dll
iop_nav.dll
prx_main.dll

My gaming PC is brand new, has over 1TB free on each of its drives.

I installed software to default locations.

Appreciate any help.
Thanks.
Cal
