Crystal Reports 9 over network: slow initialization


We have a VC++ application that uses Crystal Reports RDC (actually 8.5, and trying to change to 9.2). By design our application is installed on a file server and users execute it directly from the server, without copying or install any component in the local drive. We just register the minumum Crystal Reports DLLs needed to point directly to the location of this DLLs in the server. So we don't copy any Crystal Reports Runtime DLLs to c:\

At this time, with Crystal Reports 8.5, the minimum runtime DLLs on the server needed to run our application and print reports have a size of 8Mb, and the first time our application tries to open a report it hangs for about 5 seconds (with FileMon I see that Crystal Reports is loading its runtime DLLs). But now I'm trying to change it to use Crystal Reports 9 (due to unsolved CR8.5 limitations). With this version our minimum required runtime DLLs have a size of almost 12Mb, and the load time of this DLLs become almost 10 seconds (too big).

I did tests with Crystal Reports XI and it was even worse. If I copy and register the DLLs in the local drive it loads very fast, but we need to make it to work directly from the server without copying the files to c:\

Is there any way to reduce the loading time of this runtime DLLs without having to copy them to the local drive? Thanks
