I tried to install Staad Foundation Advanced with stfad0700*****.exe. I can't open the software and it prompts "C:\Staad Foundation Advanced 7\XMlLite.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support." I tried to reinstall the program but it still did not work properly and prompted the same.
Search for xmllite.dll file in your local computer; most likely you will find it in \System32 folder. Go to STAAD.Foundation Advanced folder and rename or delete the XMllite.dll file. Run the program, it should work fine.
