Win7 (32bit) to Win7 (64bit) upgrade install error

[Bpaul9999]

Hello

I have purchased and downloaded both 32 bit and 64 bit Windows7 Professional (no CDs or media here only download version)

I sucessfully upgraded from Vista 32 to Win7 32

Then I upgraded my hard disk (140Gb 500GB) and RAM (3GB to to 4GB)

Now I would like to go from Win7 32bit to 64bit

When I try and run the Win7-P-retail-en-us.x64.exe file it upacks the box then stops with this error:

"We are unable to create or save files in the folder in which this application was downloaded. Please check the folder properties to make sure that you have security permission on the folder to write flies and that that folder is not read only"
​

I am the System Admin and I have full rights, and have moved the exe and the setup box files to My Documentsand I have modified the directory properties/attributes but I still get the same error over and over.

I searched the posts and some people stated one needs a clean install others say you can upgrade from any version so I am trying the upgrade here especially since the upgrade from Vista 32 to Win7 32 was smooth and did require all the extra work of a reinstall.

Can someone help me here?

Thanks

I believe to go from 32-bit to 64-bit, you will have to boot off the DVD. The installer is a 64 bit application that won't run under 32-bit. Find instructions to create a DVD if you don't already have it.

Good luck!
