The problem faced
Whether you are using an SSD to boost the performance of your system or have simply opted for Office 365 business or student from their website, you will find that you cannot customise the installation, and all the tools are installed on default C: drive. This is because, from Office 365, Microsoft has implemented the Click-to-Run technique of installing software. What this does is that once you click on the file the installation happens by itself, and you cannot tweak it in any way. This has caused many users to express their resentment. People pay sums of $99 for this product and then find themselves unable even to change the install directory. Many people don’t have the required near approximate 4 GB of space in their default drive, so they absolutely need to change the install directory. Worry not, because we will tell you how.
Method 1: Changing install directory
You can change the install directory to some other path by making some modifications in the Registry. Here’s what you need to do: In the Start menu or Run, type regedit Make your way to the following under Registry Editor: Look for a value named ‘ProgramFilesDir’. Change the default value, which will be ‘C:\Program Files’ to the new location you want Close the regedit and restart your system so that the change takes effect
Method 2: Create a junction to point to some other location
The operating system thinks it is going to C: drive to run Office but it is going to your new location. Note that this method only works if you want to move Office Suite to a new location, meaning that you already have it installed on your C: drive. Here’s how this works: Empty the recycle bin Run Task Manager and end all MS Office related tasks Find the directories ‘C:\Program Files\Microsoft Office 15’ and ‘C:\Program Files (x86)\Microsoft Office Delete both of these directories Open command prompt and enter this: Restore the deleted files from recycle bin. They now appear in your new drive instead of C: MKLINK /J “C:\Program Files (x86)\Microsoft Office” “(your_preferred_disk_drive):\Program Files (x86)\Microsoft Office” Reboot your system Microsoft really annoyed a lot of people with their Click-to-Run implementation. If you use any Office version other than MS Office Professional Plus 2013, you cannot customise the installation. Using the methods described above, you can change the install location.
