Running 64-bit 2.9 under Windows 7, single-user install. For some reason, when I try to rebuild formats, I get a message to the effect that
'The MikTeX configuration utility failed. Do you want to see the transcript?'
If I click 'yes', I get the following:
initexmf.EXE: The operation failed for some reason.
initexmf.EXE: Data: C:\Users\egc\Desktop\egc\text\MikTeX\miktex\bin\x64\miktex-makefmt.exe
Any suggestions as to what I need to do to resolve this?
