installation failed

[maurizio]

Hello everyone! I tried to install pro tools first on my pc but at the end of the installation, when everything seems to be fine, it gives me an error message explaining the lack of an "api-win-core-winrt-string- 1-1-0.dll
in my pc it already runs cubase without problems, I have 8 Gb of ram, solid disk, pcie e-mu card, quad core x 3800, s.o. win 7x64
I searched the web for this file to insert it but my antivirus tells me "dangerous page" I tried the installation 3 times but the result is the same as the previous one. has anyone had the same problem?
Thank you for your time
