Remote debugging Tools Cannot Install on Surface RT Running 8.1 Preview (cannot verify digital signature)

Question

I am trying to install Remote Tools on a Surface RT running Windows 8.1 preview. I downloaded update 2 of remote tools from Microsoft's site and when I try to run it I get the error:

Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.

This is confusing because I downloaded the file directly from MS website and when I look at the .exe properties it says digital signatures by Microsoft Corporation.

Any insight would be greatly appreciated.

Thanks!

Update: It seems like my Microsoft Root Authority certificate is "not valid for the selected purposes" I've tried exporting a "good" certificate from another machine and importing it into the Surface machine but it still gives the same issue.

Answer 1

This is because your downloading the 2012 tools. You can download the 2013 preview tools here at the following link! (Be sure to choose ARM)

Would have been nice if Microsoft had given us a heads up.

Answer 2

Also, when I go to the 2013 download on my Surface RT running 8.1 preview, and I click on Download, no matter which option I pick (x86, x64, or ARM) it downloads the x86 version, which obviously won't work. I had to download it on a PC and copy it over using a USB drive.
