While attempting to install the software from the downloaded file a "Not enough space on drive C:\ to extract this package" message is displayed and installation cannot continue.
In some cases, this message is false. Try the options below in the order they are listed.
Ensure there is actually enough disk space to install the application.
Reboot the computer on which the software is to be installed, then try installing again.
Use Windows Explorer to create a new folder in a convenient location.
Download and install 7-Zip (http://www.7-zip.org) if not already installed.
Open 7-Zip File Manager.
In 7-Zip File Manager, browse to the downloaded .EXE installation file that gives the error message and right-click it. Select Open Inside from the pop up.
Select all the files and folders this reveals and drag them from 7-Zip File Manager to Windows Explorer focused on the new folder created in step 1.
Run the setup.exe file extracted into the new folder by double-clicking in Windows Explorer or by using Run (Windows+R). This should install the software without the "Not enough space" error message.
