Lỗi an instance of product cannot be loaded

I am trying to create a symbolic link on my win7 64bit machine to redirect the iTunes backup data to another drive. I am pretty sure the syntax is correct but cannot understand how to clear this error. I have tried both commands below which have the same error. I am running in Administrator Command Window. Could there be some corporate group policy preventing me from running this command?

mklink /D "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Apple Computer\MobileSync\Backup" 

or

mklink /J "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Apple Computer\MobileSync\Backup"

Error

Cannot create a file when that file already exists.

the syntax is incorrect.

mklink /J "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Apple Computer\MobileSync\Backup"

3 has the following synatx:

mklink [options]  

mklink /J "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Apple Computer\MobileSync\Backup"

4 is the file/folder that exists, and

mklink /J "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Apple Computer\MobileSync\Backup"

5 is the created one that links to the target.

so the command should be:

mklink /D "E:\Apple Computer\MobileSync\Backup"  "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup"

See the Microsoft Documentation for mklink usage.

The simplest way is to delete the

mklink /J "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Apple Computer\MobileSync\Backup"

6 folder in the original

mklink /J "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Apple Computer\MobileSync\Backup"

7 folder on the

mklink /J "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Apple Computer\MobileSync\Backup"

8 drive, but leave the

mklink /J "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Apple Computer\MobileSync\Backup"

9 folder be. This is because you're trying to fake the existence of the

mklink /J "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Apple Computer\MobileSync\Backup"

6 folder (so it must not exist already), but you also need its parents to exist.

Then, if we run the command:

mklink [options]  

1

Windows will hence create a hard link shortcut

mklink /J "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Apple Computer\MobileSync\Backup"

6 on the

mklink /J "C:\Users\odellt1\AppData\Roaming\Apple Computer\MobileSync\Backup" "E:\Apple Computer\MobileSync\Backup"

8 drive.

I had the same issue with the

mklink [options]  

4, until I used the

mklink [options]  

5:

mklink /J "%APPDATA%\Apple Computer\MobileSync\Backup" "E:\iTune Backups"
Junction created for C:\Users\Me\AppData\Roaming\Apple Computer\MobileSync\Backup <<===>> E:\iTune Backups

Note: Make sure you use straight quotes, otherwise you get a syntax command error.

I just wanted to add that the error you mentioned in your comment above

mklink [options]  

6 appears to happen when you are symbolically linking at a folder sub-level which doesn't exist at the link's original source.
