ExtractTemporaryFile checks only filename and not path name

Actually ExtractTemporaryFile checks only the filename not the path. If you have multiple files with same name on different directories you need to rename files and add DestName parameters to the [files] entries if you need to use ExtractTemporaryFile . With a second parameter (sourcedir) it should possible distinguish different files.

Here's a workaround:

[Files]
Source: "a.exe"; DestName:"b.exe"; Flags: dontcopy

Then pass "b.exe" to ExtractTemporaryFile.

Maybe an alternative is to give each entry an ID (optional) that can be used in ExtractTemporaryFileID()?

Setup doesnt know about source dirs.

I suggest you ...
