Installation failure

I have tried to install the 2D software several times in Windows XP. It unpacks ok, then says it cannot find a file _isXX.tmp, where XX is a number that changes each time I try to install it.

This happened after it had me install Microsoft .NET framework 2.0. I had to reboot at that point after .NET installed.

The installations stops with the message it cannot find the _isXX.tmp file.
