Digital Edition 4,5/window 10 quit. Have reinstalled no good. Deletes itself .

ADE 4.5 workwd with W10 for some time. Suddenly quit. Trouble shooting no good. Reinstalled. Now won't even open. Under "Details" after installation all lines show green and last entry is "completed". I hit "close" on setup window and new green line appears that reads in part "delete file: c/program files (x86) adobe/adobe digital editions 4.5/migrat....."

I am not very techy by the way
