Hello,
just simple suggestion:
add /wxsfile (or simmilar) into regpkg tool for generating registry lines into something, wix could include (via <include>). reg file is handy, but not directly loadable by wix (afaik).
Thanks!
BTW: I really begin to like VSIP. Mine second day with it, and slowly falling in love :)

I'm sorry, that site have some problems with direct links. Try this one instead (no direct link either... :-\ )

If someone is interested, I have Python script, which transforms .reg (or .vrg) file into .wxs, which one could simply include in main wix script and got all registry entries needed.
Its pretty simple and straightforward to satisfy my needs (not something generally useful) but maybe with some small modifications (change constants mostly) it could be found useful by others as well.
For those who want give it a try, here it is.
btw: I didn't try to run it via IronPython, but it should just run fine :-)
