We got a report from a customer that claims that my component (DLL) written in C# will not load unless the user running the program has administrator access. The problem comes when the DLL is actually loaded into memory. As far as I can see, I'm not doing anything special here. I pretty much just do a lot of low level numeric manipulation, as well as using the Collections library and a few unchecked arithmetic code blocks. Anyone have any ideas about this?

Can you reproduce it locally under a restricted account?

Do you do any registry access or access any system folders, ie program files, or Windows.

I have found that if you need to access an AccessDB or configuration files that are in the system directory (Not the app.config) you need to have access to the directories.

I should have followed up at the time.

It was a dumb mistake on my part, I was making a log file in the root of C:\. This isn't allowed as a normal user.
