create folder(trusted), copy of MDE and shortcut - vbscript

Question

I have put together a script that I think will work, but the only code I know is some VBA. Never tried to create a vbscript before, so my apologies if some errors are obvious, but pointers and corrections would be appreciated.
I am hoping I can give users in my company a link to this script and have them run it. It will create a folder on their C Drive, make it a trusted location, copy a database frontend from the server into it and create a shortcut on their desktop linking to the new file. (I'm hoping the file will auto-update when a new version is made - I think that bit works though).
The code comes from various sources, including my own addled mind but would I need to download Visual Studio to test this? Slightly concerned as it includes creating a registry key and I don't know how to stop the code if it all goes horribly wrong. I don't even know how to break a loop (although I think I read somewhere you need to hit Esc twice). Any tips on how to signify which sub is the main one to run on start would be good too.
EDIT : Code has been amended to my end result incase it is of use to others. Please use with caution. The 'update' vbs deletes the folder created on the local drive.

There is also a separate Update vbs which is what runs when the link is clicked. This checks to see if the 'created date' of the database on the server is newer than that on the local drive. The new DB name MUST NOT be the same as the one it is replacing. It might run a little fast, but this is as far as I have taken this.
