Well, I found my mod and it looks like CubeCart is going to work. (Even modded my mod

) I have found CC to be quick and stable (so far) on Windows. We did have to comment out the Set the SQL mode to strict sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"in my.ini in order to upload images, (tip of the hat to Goober999) but no other changes from a standard MySql 5.0 / PHP5 install have been made thus far. Cubecart has run flawlessly through 10 test orders with a total stock of 6 products. All aspects of the store seem to be workng flawlessly at this point.
The next step is to install the SSL certificate and continue the test drive. At this point, it seems there are no technical reasons why CubeCart will not work well in a Windows environment. I will continue to post my progress.
