I took the windows 64 bit clienttools and installed on my Windows 10 box. I noticed that it defaults the installation to "Program Files" and not "Program Files (x86)". If this is the default behavior we need to change the build scripts so that the install dir mimics this behavior. That way when we do replacement in scripts like esdl.bat.in we have the correct directory structure. The other option would be to change the esdl.bat call to be a relative path. This might be the better option.
