Change Default File Partition For Installing 32-Bit Files on Windows 7
 

I am trying to to install software on another partition (change from C: to E:). I changed the values in the Registry Keys ProgramFilesDir and ProgramFilesDir (x86). This seems to work when installing 64-bit software, however, this does not work for 32-bit software.

For example, I was installing Adobe CS6 which contains both 64-bit and 32-bit software. The installation wizard selected the proper partition to install the 64-bit portion of the software E:/Program Files/Adobe but installed the 32-bit portion of the software in C:/Program Files (x86)/Adobe.

Am I missing something from the tutorial? I am trying to keep my software separate from my main partition.

Also should I be modifying my CommonFilesDir, CommonFilesDir (x86), CommonW6432Dir, ProgramsW6432Dir values to reflect K: instead of C:?

Did you check the keys under the "Wow6432Node"? This is a duplicate basically of all the 32bit registry keys that exist on a 64bit machine.

Most people just change where the software installs during the installation routine though rather than modifying the registry.
