I used the contact form for a more specific version of the question but might manage to work around the problem using another approach:
When using Portable Apps (such as Chrome Portable for example) as part of the software package that should be installed the directories "Program Files" / "Program Files (x86)" cause some problems.
In my case I'd be ok with it to ask the user to install it anywhere expect (!) those directories but I don't know how to manage this with the given interface.
There's the read-only checkbox but that forces the user to one specific location (for example C:\DEMO). They user should have the freedom to choose the directory he wants (for example E:\TEST)... he just has to avoid the Program Files directories because of the right constraints.
How to do this?
Thanks in advance!
