Yes, wave1 (Polish) I try to slipstream SP1 64-bit with 64-bit version (Windows Vista Business) (LRMCxFRE_PL_DVD), and I got the same error I have LRMCFRE_PL_DVD and LRMCxFRE_PL_DVD from my high school MSDNAA program. ----- EDIT ----- Problem solved. I need 20 GB free space on system partition and copy installation files to vLite folder in Program Files.
