JSI Tip 0151 - Problems with 16bit apps in WinNT?

Here are some reasons for having problems with 16bit applications:

1. The PATH variable is too long or has an entry pointing to the WINDOWS or WINDOW/SYSTEM directories of a Windows 3.x or Windows 95 installation. This would be in either Control Panel / System / Environment or the AUTOEXEC.BAT. See tip 021.

2. The COMMAND.COM used by Windows NT is missing, damaged or replaced by another version. Repair System files and re-apply your latest Service Pack.

3. The VER.DLL file in the %systemroot%\system or %systemroot%\system32 directories is corrupted or replaced by an invalid version.

4. SHARE.EXE (or VSHARE) is being loaded in an %systemroot%\system32\AUTOEXEC.NT.

5. Insufficent environment space, see tip 047.

6. Check %systemroot%\system32\CONFIG.NT, here is mine:

dos=high, umb
device=%SystemRoot%\system32\himem.sys
files=75
shell=%systemroot%\system32\command.com /p /e:4096
ntcmdprompt

7. Corruption of the WOW sub-system files. Repair System files and re-apply your latest Service Pack.

8. Make sure the following files are from your latest SP or NT CD, whichever is later:

        Commdlg.dll
        Compobj.dll
        Ddeml.dll
        Ole2.dll
        Ole2disp.dll
        Storage.dll
        Ctl3dv2.dll
        Ole2nls.dll
        Stdole.tlb
        Typelib.dll
        Ver.dll

NOTE: Ver.dll should be in both %SystemRoot% and %SystemRoot%\System32.
