incorrect or no genesis block found. Incorrect data folder for the network?

friend got this error message trying to install on Dell laptop with windows10, I installed on same laptop last week with no problem.
tried uninstall and reinstalling
tried turning off virus protection, firewall, adblock.

any suggestions?

uhadme “Incorrect data folder” is the biggest key. Completely delete all the files and folders associated with Reddcoin and try a fresh install.

yes, I have tried the uninstall/reinstall. searched for reddcoin files. unable to locate whatever is blocking this download/sync

I created a new user account on the laptop.
and downloaded the wallet to that profile.
it has past that error message point.

hope this fixed the issue
