When i try and install programs or aplications and it comes to a .bat file, ect. It tells me the file is corupt when i know it isnt, does anyone know whats wrong with it or how to fix it?

What installer system is being used? Is this for one installer or a whole set of different ones? Are you just installing the software or making an installer for software? Your post tells us next to nothing - we can't help without information!

When it comes to a .bat file, ect. Whilst im installing software, eg- a game, itunes or other sort of aplications. The CRC tells me the file is corupt, i know its not corupt media because i've tryed installing these same programs on other computers and it worked fine. And its always files like .bat.

The batch file just installs the other (larger) files, any CRC error at this point usually means you have defective RAM in the PC.

Try reinstalling the Windows installer if you can (I can't test it here).

run a ram tester, memtest86 or windiag, and also run a manufacturers diagnostic on your harddrive....

GF's suggestion of bad memory is still valid: the mention of .BAT files perplexed me. ;)

CRC errors are very often an indicator of bad memory. Downloads should produce an error message if something has gone amiss in the transfer; reading a disk should give a disk error message. .CAB files are compressed, and carry a CRC (cyclic redundancy check) code which is compared with the result of a calculation carried out by the decompression utility. Decompression requires a perfect file. If the file (as "seen" by the utility) isn't exactly correct, you will get a "CRC error". The commonest cause of that is bad memory. It might mean that the decompression is using memory areas which isn't usually in use (.CAB files are often big -- that's why they are compressed) or areas which usually just contain (and corrupt) data, which frequently does no harm, except causing programmes to give wrong answers. :groan: If you are lucky, it will crash the OS. :D

So test the memory.
