It is possible to run version 1.3 and 2.0 together at one Windows machine. I did it with Windows 2000. But It's not possible to install (!) two versions 2.0x together at one machine. This problem may depend on the product code used for creating the MSI files. I'm not sure, if each new minor version has its own product code. The installer uses this code to identify the software, so changing the product code may fix the problem. But changing it for each minor version does also mean: designate each minor version as a different product. Kess
