My development environment is VS2012 on a Win7 machine. My client is running XP.
I have an existing solution with an executable and 4 DLLs. It is built on the 3.5 framework. It has been running for years and was last touched about 7 months ago.
I made a change today in the exe and 1 DLL (changing an ftp client to use ftps instead of ftp).
The solution runs fine from the development environment, and the exe runs fine from the bin/release folder on my machine.
When I copied the exe and the DLL to my client's environment, not only did I get the message shown in the title, the client's antivirus deleted the executable and the shortcut to it.
What could be going on?
