office setup.exe not found

I am installing a DL of office 2010. but midway through the installation it asks 4 the setup.exe location.???????? what next.I found the folder but it didnt accept it????? where to get a working file 4 setup.exe 4 office pro 2010?

 

thanks for your reply. It verified. But the DL was interupted then restarted. I was hoping not to have to DL again. Its a lame wireless signal I have. Ive done the same w/ other similar issues of missing files b4. But I couldn't seem to find proper setup.exe. But I did resolve this morn.
I copied it off a friends pc that had used it successfully. The file, not the program. Worked.
