Error message: Impossible to execute Studio on this PC

Hi all,

I have tried to open Studio on my laptop (the same I always use) and got an error message: Impossibile eseguire questa App nel tuo PC. Per cercare una versione per il tuo PC contatta il distributore del software (impossible to execute this app on your PC. TO look for a version for your PC get in touch with the software's distributor). I am clueless and don't know what to do. I have tried a Studio repair but the option is not there; I have looked for the AppData folder as instructed by SDL support but it's not there. nyone who has an idea on what might have happened? What if I remove the software and re-install it? 

Thank you in advance for your help.
