Windows Err Msg: Application Execution Error


The information in this article applies to:

  • Microsoft Windows versions 3.1, 3.11
  • Microsoft Windows for Workgroups versions 3.1, 3.11


When you try to run Windows Setup or File Manager in the Main group of Program Manager in Windows 3.1 or Windows for Workgroups 3.1, you receive the following error message:

Application Execution Error
One of the library files needed to run this application is damaged.
Please reinstall this application.


This error message is displayed if VER.DLL, LZEXPAND.DLL, or COMMDLG.DLL is corrupted.


To correct the problem, do the following:

  1. Quit Windows or Windows for Workgroups.
  2. Delete VER.DLL, LZEXPAND.DLL, and COMMDLG.DLL from your Windows directory or Windows SYSTEM subdirectory.
  3. Insert the disks with the files VER.DL_, LZEXPAND.DL_, and COMMDLG.DLL in the floppy disk drive. The files are located on the following disks:

       Disk Size    Filename      Win 3.1   Win 3.11   WFWG 3.1   WFWG 3.11
       5.25-inch    VER.DL_        Disk 2     Disk 3     Disk 3     Disk 2
        (1.2-MB)    LZEXPAND.DL_   Disk 1     Disk 3     Disk 3     Disk 2

                    COMMDLG.DL_    Disk 4     Disk 4     Disk 5     Disk 1 
  4. Type the following at the MS-DOS command prompt (provided the source floppy disk drive is A) and press ENTER after each line:

    expand a:\ver.dl_ c:\windows\system\ver.dll

    expand a:\lzexpand.dl_ c:\windows\system\lzexpand.dll

    expand a:\commdlg.dl_ c:\windows\system\commdlg.dll
