because you are trying to run it as an administrator...and it is not install under Admin..you must have it installed as a User and not Admin.....do this instead...
make a batch file for qt in the folder you have qt installed in...
example for shortcut to QT saved on desktop:
Right click and go to "Open File Location"
now in that folder...right click and go to "create new test document"
start litecoin-qt.exe --reindex
now go to "File"..."save As"......Selected "All Files" instead of .txt and save it as "start.bat"
now double click the batch file to open litecoin-qt with the command
if it still says that then you'll need to move the right click the batch file or QT and "run as Administrator" then close it and try again as non admin
