I did try this solution before asking the community, with no results.
I did resolve the situation, and is not related with a missing or corrupt file as suggested by Garmin product support.
SOLUTION:
download BaseCamp.exe file, than use a compress tool like 7-zip
right mouse click on the file to open file and see elements in the exec file
look for the BCMAIN.msi file, double click, it will then install,
after you can then go back to the normal BaseCamp.exe
it will then install nicely
thanks for the help
