I understand I can download the programs directly from the Sony Support page. I am more worried about whatever is causing this problem because I think it is affecting other programs such as iTunes like I stated. I could be wrong though and don't have much to test to see if it is the same problem.
When downloading updates for my laptop with Sony Vaio Update it downloads almost the whole file(maybe not a few kbs but I would say atleast 99% of the file) and then gives me an error (please wait a while, then try again). Vaio update works fine on my mom's computer which is on the same network...
