I have purchased and downloaded Windows 7 Professional x64 from Microsoft in three files (one .exe file and two .box files). I do not know how to use the three files to install Windows on another computer using a flashdrive and Microsoft's tutorials are useless.
Thus far I have tried to unblock each file, unselect the readme option, and open the .exe as administrator but then I get a "Unloading the Box Error" that says:
THE APPLICATION CANNOT FIND ONE OF ITS REQUIRED FILES, POSSIBLE BECAUSE IT WAS UNABLE TO CREATE IT IN THE FOLDER. PLEASE MAKE SURE THAT THE FOLD IN WHICH THIS APPLICATION WAS DOWNLOADED IS ACCESSIBLE AND NOT READ-ONLY.
Microsoft's instructions don't work b/c I hit the message I posted earlier.

On the Downloads + Product Keys page, find the Windows product that you purchased. Select the download option (32-bit or 64-bit) and file type EXE.
Note: You should only choose the ISO file type if you want to install Windows 7 on a different computer than the one you are currently using.
Click Download file 1. In the download dialog box, click Save.
IMPORTANT: You must download all three files to install Windows 7.
When file 1 has finished downloading, click Download file 2. In the download dialog box, click Save.
When file 2 has finished downloading, click Download file 3. In the download dialog box, click Save.
Note: Your downloaded software files are saved to the following default location: C:\Users\Downloads
When file 3 has finished downloading, click Run in the download dialog box
In the installation window, click Install
Follow the instructions in the installation wizard
