It sounds like you may have some applications purchased under another Apple ID. I would recommend finding the account name of the Apps that will not transfer and authorize the computer for that account. To find the account name, see the section labeled Authorize using the correct account name in the article below. Alternatively, you can either Right-Click and Get Info on the selected App for Windows or Control-Click and Get Info for Mac. The Apple ID that was used to purchase the App will be on the Summary tab.
Hope that helps.
Wow, thank you so much. You just completely solve my problem, but one more thing please. Those apps that I want to transfer is from my old Apple Account, I rencently using a new account now so how can I transfer those apps to my new pc by using Home Sharing of my new Apple Account which is the one that I'm using right now.
In order to transfer the applications purchased with the old Apple ID, you will need to authorize the new computer with that ID before you will be able to Home Share them. If the password is not remembered for that account, you will need to reset the password. Here are the steps that will walk you through that process.
If you experience issues, see the last section labeled Additional Information.
