Why do I receive the "This product must be installed to Q:. Ensure that Q: is unused and try again" error when I try to use Office Starter To-Go on my computer?
This error means that the

Q: drive letter cannot be made available, you cannot use Office Starter To-Go on your computer.
Why do I have a "Q:" drive when I use Office Starter To-Go?
Office Starter To-Go uses the Office Click-to-Run technology that must use a virtual application drive. This virtual application drive is why you have the Q: drive.
What is the "Q:" drive?
Office 2010 Click-to-Run suite such as Office Starter 2010, Office Starter To-Go, Office Home and Student 2010, and Office Home and Business 2010 are based on some application virtualization technology. The Q: drive is the virtual file system drive where virtualized applications are located in the file system namespace. This Q: drive is not a typical drive. The Q: drive has no space that the user can access directly and is inaccessible from Windows Explorer or My Computer.
Are my Office documents also stored in this "Q:" drive?
By default, Office saves your documents in the
My Documents folder.
Caution We strongly recommend that you do not save any Office documents on the
Q: drive for the following reasons:
- The Q: drive cannot be accessed from Windows Explorer directly.
- If the Office installation files have to be repaired, the Q: drive may be removed and recreated. Therefore, any Office documents that are stored on the Q: drive are lost.
Can I hide or delete the "Q:" drive?
No. Any access to hide or to delete the Q: drive is removed.
