Hi Sudeep, Here are the MSCDEX files. There is a TSR and a VDD. I normally build the TSR with 16-bit tools. The only installation changes required would be that the TSR (MSCDEXNT.EXE) be added to the Autoexec.nt. This line in autoexec.nt needs to be before the "dosx" line, per a bug in dosx. The VCDEX.DLL needs to be in the path. The MSCDEXNT.TSR does a RegisterModule() to it. I have a couple of CD player apps in the TEST directory. CDP is a win16 app, and CDPLYR is a DOS app (from the soundblaster disks). Both of them use MSCDEX exclusively. I hope that does it. Let me know if you run into any problems. -Neil
