I want to install Cyber Protection agent on an industrial pc with Windows 7 embedded Standard x32 installed. However, when the installation reaches 28%, it gives the error "Invalid Drive A:\" as in the attachment. There is no drive A on the PC. I had this problem on 4 different computers with the same operating system installed. Can you help me?
