I have the same issue. Unblocking the Zip file didnt help for me.
I am 32 bit, and app default pool is applied.

This threw me off as well. I converted two sites on my local install without any issues, but when I started upgrading my hosted sites, I started getting server error messages. I finally tried the unlock zip file process and redeployed all the files and it started working.
"This file came from another computer and might be blocked to help protect this computer"
Apparently, this started way back with XP SP2 and Vista SP1.
When you download files Windows appends a "Zone Identifier" alternate data stream (supported in NTFS) to each file. If it's an archive, when you expand it each file within will also have the identified appended. The Windows shell is aware of this stream and this is the reason why the message gets displayed in the file properties dialog. Once you "Unblock" the stream is removed. IE is also aware of this alternate stream and it won't allow any code / .htc files to execute if they have the stream appended.
Here's a handy utility to remove these:

Another solution is to copy files to a drive formatted with FAT and back. The alternate data streams can't be saved to FAT and get stripped.
Just another way that MS is looking out for us. It's one headache or another I guess.

Baden, you may want to check the file system has appropriate permissions on.
To start with add "everyone" with full permissions to the nop folders only and the IISreset and check again.
If that works, you know its a permissions issue and then start by removing everyone permissions and then adding NETWORK SERVICE and any other accounts your using for the app pool identity and the IIS_WPG group.
