Yes the Q drive is associated with Click to Run (CTR).
CTR is a PITA for the average home user. I can see it as a valid approach for a corporate/school network, but not wasting bandwidth for home user.
The way to make the Q go away is to uninstall the CTR and download and install an equivalent MSI version of office.
You need the product key to do the installation (so it does not apply to Starter which is OEM only).
What is Click to Run
Click-to-Run is a new Electronic Software Distribution (ESD) technology for Office 2010 that utilizes Microsoft’s streaming and virtualization technology. Click-to-Run provides a much faster and simpler download and installation experience for customers
trying or buying Office 2010 over the Internet. Click-to-Run allows customers to maintain multiple versions of Office so customers can easily try Office 2010 side by side with an existing version of Office. Click-to-Run automatically downloads and installs
any software updates when connected to the Internet, helping to maintain a more secure and up-to-date Office experience. At this time, only Office Home and Student 2010 and Office Home and Business 2010 will be available through Click-to-Run and limited based
on broadband speed requirements.
NOTE: CTR is a relatively new approach to installing and running Office. Introduced with 2010. So very few technicians are aware of it, let alone familiar with trouble shooting it. As well, it introduces
a whole new set of errors, like the one that you encountered. My personal recommendation is that unless you have a clearly identified need for it and explicitly requested the download, DON’T USE IT.
Overview of Microsoft Office Click-to-Run for Office 2010
Microsoft is offering a new way to download and install products of Microsoft Office 2010. This technology is called Microsoft Office Click-to-Run, and this article discusses how Office Click-to-Run works and lists some frequently asked questions (FAQ).
Introduction to Office Click-to-Run
Office Click-to-Run is a new way for broadband customers to obtain Microsoft Office and to update Office 2010. Office
Click-to-Run uses the virtualization and streaming technologies of Microsoft.
Office Click-to-Run Technology
Office Click-to-Run products use streaming technology that is similar to watching a video on the web. When you watch a video on the web, you can watch the first part of the video before the whole file is downloaded. Similarly, you can start using Office
2010 before the whole suite or product is downloaded when you use Office Click-to-Run. Therefore, the rest of Office 2010 is being downloaded in the background quietly while you use one part of Office 2010.
Office Click-to-Run products also use Microsoft virtualization technology that stores Office 2010 in virtualized application space. This virtual space separates Office 2010 from the regular file system and from the other applications on your computer.
This separation lets Office 2010 coexist together with any existing version of Office that is already installed on your computer. There are also other benefits to Office Click-to-Run. For more information, visit the following Microsoft blog website:
