Error L6218E in ADS 1.1 on Win7 x64

In my first installation of ADS, I installed it into the default location specified by ADS. Because ADS itself is a 32 bits program, it installed to "C:\Program Files (x86)". However, installing ADS to this location brings the issue shown in above image.

To resolve this issue, just simply install ADS to "C:\Program Files".
