windows - error : output module .mov after effects

When exporting a Quicktime movie from After Effects on windows 7, I get the following error ...

After Effects error: Rendering error while writing to file "(my main internal drive / my file name).mov". An output module failed. The file may be damaged or corrupted. (-161-153464).

I see a lot of suggestions for limiting the number of processors by using "msconfig" to change the "boot" file. This seems like a poor solution because it affects how all other programs use the processors.

Does anyone have any other help on how to resolve this without reducing processors ?

Thanks, for any help.
