Hi All, My client recently upgraded their O/S from a 32-bit to Windows Server 2008 R2 (64-bit), which breaks certain functionality of our product. Our product uses a third-party 16-bit application (pl.exe) command line utility that returns a listing of files in a directory. Because this product I am supporting is a very old product, which exists before my time, I am not able to find any updates or relevant information regarding "pl.exe" and I did the necessary initial findings (from colleagues, etc). I tried looking for a MS-DOS emulator which I came across as "MS-DOS Player for Win32-x64" (http://homepage3.nifty.com/takeda-toshiya/msdos/index.html) but doesn't work well for my product. Hyper-V does not support Windows XP Mode which I initially have in mind to pass the parameters into Windows XP Mode and triggers "pl.exe" within. I have discussed with my management and all agreed that recode is our least priority now as this is a very old product. Nevertheless, the following shows the syntax and output of "pl.exe" utility, Syntax: Usage: PL [d:][path] Sample output: "BROWSE.BAT 0000000000 2014/04/02 18:29 32 115978240" "BROWSE.COM 0000000002 1990/05/08 00:00 1010 115978240" "CAT.BAT 0000000000 2014/04/02 18:30 29 115978240" "CAT.COM 0000000029 1992/10/06 17:32 9058 115978240" "LP.BAT 0000000000 2014/04/02 18:30 28 115978240" "LP.EXE 0000000050 1992/08/18 10:35 13564 115978240" "MSDOS.EXE 0000004700 2014/04/15 00:32 390656 115978240" "PC.BAT 0000000000 2014/04/02 18:30 28 115978240" "PC.EXE 0000000123 1993/12/21 08:51 16316 115978240" "PL.BAT 0000000000 2014/06/02 14:59 30 115978240" "PL.EXE 0000000116 1993/12/28 09:21 15418 115978240" "TEST.TXT 0000000000 2014/06/02 15:03 32 115978240" "TEXT.TXT 0000000000 2014/06/02 15:06 0 115978240" Do you guys have any alternatives to this 16-bit utility, or have experience of any similar cases? How do you guys deal with it? Much thanks!
