Make sure that you are using the correct tool path (i.e. installutil.exe) for installing the application.

This issue normally occurs when we attempt to use 32 bit (/platform:x86) version of the tool to install a 64-bit application or a 64-bit (/platform:x64) version of the tool to install a 32-bit application.

Just confirm the path you are using is correct. There is a slight difference in both paths.
