Access denied to access path... "Dati applicazioni"

Dear All,

 

Out of a sudden SDL Trados Studio 2017 stopped allowing me to open clients' packages. The message I receive is the following: "Access to the path ‘C:\Users\Antonia Tofalo\AppData\Local\Dati Applicazioni' denied." I tried to find this folder but I do not manage to! Even dethicking the flag to "Show hidden folders".

Can you help? Thanks in advance,

 

Antonia
