XANA Avenue 1
Not only can you have multiple copies of XANA House 1 on one hard drive, but you can switch between them, using this add-on.
In order to make this work :
1) Create a second copy of the XANA_House_1 folder that is located in your C: drive, then rename it "XANA_House_1_2".
2) Download this add-on, extract the .ZIP file, then move the extracted XANA_Avenue_1 folder to your C: drive (See Figure A).
3) Launch XANA House 1, then click on Exit, then click on Go To XANA Avenue 1. The add-on will generate a house icon for every copy of XANA House 1 that it can recognize.
4) Click on a house number. For example, if you click on House #2, the add-on will launch the copy of XANA House 1 that it thinks is the second copy.
5) You can keep creating more copies, up to the point that you have a copy called "XANA_House_1_10". (See Figure B).
It is okay to have more than 10 copies on your hard drive as long as you realize that this add-on will not be able to recognize those additional copies.
