It is also possible to bind an executable to a specific version of a DLL, that is, to resolve the addresses of imported functions at compile-time. Deleting or moving a shared DLL file to a different folder results in an inability to access the functions stored in that particular DLL file. Is there any distinction between shared objects and DLLs when it comes to C/C++ development on Linux or any other POSIX compliant OS (ie: MINIX, UNIX, QNX, etc)?

For this reason, each process has its own instance of lpvMem, which is declared as a global variable so that it is available to all DLL functions. Each process has its own virtual memory space and do not see memory of other processes. Read-and-write code sections, much like private data sections, are private to each process. This is an important reason to avoid the use of shared sections in DLLs.

Why Does It Need Fixing?If, for whatever reason, these reference counts remain after the file has been removed, then your MSI install will be preserving a count that is no longer If when you are uninstalling a program and you are asked if you want to remove shared dlls, always click no, removing these could prevent another program from running.
