I am getting an error message whenever I am installing miktex. The error message reads:
The operation could not be completed for the following reason:
The operation failed for some reason.
Details: C:\Program Files\miktex 2.9\miktex/bin/x64\initexmf.exe
I am using Windows 8 Pro x64 with media center. Previously, I was installing miktex for all users. This time I was installing miktex for only my user account which resulted in the above error message. I ran the setup with administrator privileges. Any suggestions?

program fileswhere this user has the right to write. It can give a lot of headaches if the user hasn't by default the rights needed for maintainance and installation. Beside this Juri is right: The error message often indicates a small problem at the end, e.g. withfc-cache. Test the installation. – Ulrike Fischer Feb 26 at 8:31initexmf.exe, so it is actually not the installation itself, but presumable the trial of FNDB updating. This is started with user permissions, not with administrator rights. It could be a problem of UAC. So, what already Ulrike wrote, an installation outside ofProgram Fileswould be very likely much better. – Speravir Feb 26 at 18:24
