FAQ Problems and Incompatibilities
A: This can happen if you have a faulty shell extension installed. If you have WinRAR 3.0 installed, you can download a fixed shell extension here. Please unpack to the WinRAR directory. The replacement DLL was generously provided by the RAR author, Eugene Roshal, and will probably be included in WinRAR 3.1. (For those who are interested, the bug is in the load/unload code of Borland C++ Builder 5.0!) If you don't have RAR 3 installed, you may try to remove some of the shell extensions until the error disappears.
