I wonder if there are some permission limitations with building in the 'examples' directory.

When I try to compile the counter design on my machine, it runs fine if I first copy the 'counter' directory out of C:\intelFPGA_lite\23.1std\hls\examples, and somewhere else (e.g. C:\hls_customers\forum\counter).

I've also heard of issues with mixing versions of visual studio, e.g. if you already have 2022 installed, and then try to install 2017. The recommended solution there was to remove all visual studio installations, and install the oldest one first. (e.g. first 2017, then 2022).

Why are you installing the visual C++ redistributables? The necessary libraries should be included with visual studio:
