I upgraded to Windows 10 from Windows 8.1, I had no issues mounting Truecrypt containers in Windows 8.1. However after upgrading to Windows 10 I am able to mount the TC container but when I attempt to open the mounted drive I get this error " Location is not available z:\ is not accessible access is denied" . I tried giving full read write permission for my username in that container it still did not work. I have no issues opening other containers that I created with VeraCrypt. However I am not able to open the TC container using VeraCrypt or TrueCrypt, I get the same error with both applications.
