I'am missing lots of DLL Files when compiling with Delphi 2005. Wehre can I get for example VCL50.dll ?
When do you get the errors? I just grepped about the source and can't find any dependencies for VCL50.dll.
Does it happen when you try to install the dependencies for FR (RxLib, OpenXML, etc.)? Then you will have to find a package of this tools which compiles under 2005.
Generally it should be enough to replace all entries of VCL50.dll with the corresponding version of Delphi 2005.
