when i am installing adobe lightroom student version it gets to about 99% then says
""this application has requested the runtime to terminate it in an unusual way. please contact the applications support team for more information ""
if that error message mentions microsoft c++, let me know.
otherwise, if there is no more to that error message, reset your preferences -
