Hi, I need to modify a program written by somebody else under Borland Builder C++ 6.0. The application involves calling lots of Form and it was developed under this compiler. I have been trying to install it on my new PC running Windows 10 without success. I have tried the following. Copied all the installation files to C drive. Right click on property of the installer and checked compatibility mode. When I tried to install the program in the default directory (Program Files (x86)) or a self created directory in C:, I got a installation rejected error. What can I do?
