I've been working part time with WIX for a short time and I just began using
DTF to include a custom action in our install kit. I'm using an immediate
custom action and I just want to be able to read a file that has been installed
by a previous installation in the case of a major upgrade to extract some
information. However, whenever I try to access the file, the path is internally
modified by the method's call (config.Load(path); in the code below but all
methods I'm using seem to do this ) resulting in a none existing path. I think
it's due to the way DTF execute the CLR "out-of-process" but I don't seem to
understand how it's work... Could someone explain what is happening and if what
I want to do is possible ? Since I'm not able to find any information
concerning my problem I'm beginning to think that the solution is simple and
that I'm missing something.
Thanks
Nicolas

And here is part of the code... Quite simple really...
string path = p_Session["MANAGED_SEARCHWEB_CONFIG_PATH"];
p_Session.Log("cadata : " + path);
XmlDocument config = new XmlDocument();
p_Session.Log("xml doc created");
config.Load(path);
p_Session.Log("xml doc loaded");
