the instructions have been followed , and only2 files are giving CRC errors , this would not be the case if the instructions were not followed , i would have multi errors , not just 2 and the files that crc are the ones l*.ddl and *.dll
That is why your having so many problems... you should have zero CRC errors...
What don't you get about install demo (it has to be the one linked in the read me file)
run patch file (with admin rights)
If there is a CRC error there is an install uckup...
Question 'Do you know what a CRC error is telling you...NOTE: labcenter has updated the DEMO to 8.3sp2
So don't use this patch unless you want to be in the same boat
