Change install destination folder doesn't work - Adobe Reader DC Free

[Edwin66]

Hello, I have Windows 10 Home with 64-bit operating system, x64-based processor. It is a Dell Inspiron Laptop with 8GB of RAM and Intel Core i7 processor. 

I have the install file AcroRdrDC2200120085_en_US.exe to install Adobe Acrobat Reader DC (the free version).

My C: Drive is full, but my D: Drive has about 900 GB available. I have two physical drives. 

So I changed the destination folder for the install to an empty folder on the D: Drive. 

The install almost finishes but then gives the following error. "Error 1307: There is not enough disk space to install the file C:\Windows\Installer\b36414.msp  Free some disk space and click Retry.  Cancel to exit"

This makes no sense. I have told it to install to an empty folder on the D: drive with over 900 GB of space. Any ideas of what is happening here? Thank you in advance.

Installing any software adds a lot of info to the Windows Installer database and folders. This is always on C. So are many other things. You NEED free space, plenty of it, and a tiny C drive is a bad joke inflicted by some PC makers.
