Having same issue on surface RT. in spite of trying to follow all directions here, am completely unable to run any of the files. simply get a message "This app can't run on your PC. To find apps for this PC, open the Windows Store"
this began last night after getting a Microsoft Security Essentials warning dialog while browsing the web. I didn't do anything with the dialog but did start another browser session to try and find out if this was legit. (the giveaway was misspelled words in the message).
apparently I dug the hole deeper in the process and have been getting the 'cant run app...." message ever since even when downloading the files and going to them in windows explorer to try and run., I downloaded every version of rkill and NONE of them will run.
this machine is just a couch cruiser for me so I actually went as far as doing a full reset of windows. NADA. same behaviors. I cant get the device to restart in safe mode. just hangs.
kind of at the end of my rope. any ideas?
i'll be eternally grateful!
