I tried to create a custom refresh image using recimg and got an error code 8007007b. I cannot find any information on this error. Perhaps someone knows what it might mean. The administrator command prompt windows reads as follows:

C:\WINDOWS\system32>recimg /createimage E:\Win8RefreshImage\2013-04-21
Source OS location: C:
Recovery image path: E:\Win8RefreshImage\2013-04-21\CustomRefresh.wim
Creating recovery image. Press [ESC] to cancel.

The recovery image cannot be written.
Error Code - 0x8007007b


C:\WINDOWS\system32>

Any help is appreciated.
