My company has had numerous crashes reported to windows error reporting due to what looks like an install problem. The logs for our installs are typically in the windows\temp directory. I would like to include the install log file as a "Request Additional Files" entry, however there doesn't seem to be any way to get to a subdirectory of the list of environmental Variables that are provided. The windows temp directory is not in the list of values that you can work from, so I am stuck.
In general, I don't understand how it is possible to get at almost anything of use via the "Request Additional Files". For example, the %programfiles% directory shouldn't contain any useful files, they should be in a subdirectory for your product. What am I missing?
I have no idea if this works but could you try %programfiles%/../../ (or something similar) using the know location/depth of the programfiles folder (or which ever variable you use) and navigate up to the root (by having the correct number of "../") and the add your extra from there?
So to get to C:\TempData you might have something like:
%programfiles%/../TempData
One thing to consider is that this path might vary on different versions of Windows...
Like I said, this is a suggestion...
