The comdlg32.ocx module is used by classic Visual Basic programs. This ActiveX control is responsible for the functionality of common dialog boxes in your VB application. Common dialog boxes include the Open and Save As file dialog boxes; the Find and Replace editing dialog boxes; the Print, Print Setup, Page Setup printing dialog boxes, etc.<\/p>\n

When you attempt to run a program created using Visual Basic 6.0 on a Windows 11\/10 computer, one of the following errors may occur:<\/p>\n

Failed to load control 'CommonDialog' from COMDLG32.OCX. Your version of COMDLG32.OCX may be outdated.<\/pre>\n
Run-time error '339':\n\nComponent 'COMDLG32.OCX' or one of its dependencies not correctly\nregistered: a file is missing or invalid<\/pre>\n
\"comdlg32.ocx<\/p>\n
This happens if the module comdlg32.dll<\/code> is missing or corrupted.\u00a0Let’s see how to fix the Common dialog error in your application when run on any version of Windows, including Windows 11.<\/p>\n
Resolution<\/h2>\n
<\/a>Register COMDLG32.OCX using RegSvr32.exe<\/h3>\n
First, check if the file COMDLG32.OCX<\/code> exists in the following folder:<\/p>\n
If you’re using Windows 64-bit edition:<\/p>\n
C:\\Windows\\SysWOW64<\/pre>\n
If you’re using Windows 32-bit edition:<\/p>\n
C:\\Windows\\System32<\/pre>\n
If COMDLG32.OCX<\/code>\u00a0exists in the above location, then all you need to do is register the module using regsvr32.exe<\/code> command.<\/p>\n
To register the module, open an administrator Command Prompt window and type the following command:<\/p>\n
For Windows 64-bit systems:<\/strong><\/p>\n
regsvr32  C:\\Windows\\SysWOW64\\COMDLG32.OCX<\/pre>\n
For Windows 32-bit systems:<\/strong><\/p>\n
regsvr32  C:\\Windows\\System32\\COMDLG32.OCX<\/pre>\n
You should see the following output\/message:<\/p>\n
DllRegisterServer in comdlg32.ocx succeeded.<\/pre>\n
\n
RegSvr32.exe throws the error 0x8002801c?<\/h3>\n
If the above command-line throws the error 0x8002801c, it means that the command was unable to write to the registry successfully. This happens if you run the command from a normal Command Prompt instead of the admin or elevated Command Prompt<\/a>.<\/p>\n
The module \"comdlg32.ocx\" was loaded but the call to DllRegisterServer failed with error code 0x8002801c.\n\nFor more information about this problem, search online using the error code as a search term.<\/pre>\n
To resolve the error 0x8002801c<\/code>, re-run the command-line from admin Command Prompt.<\/p>\n<\/div>\n
COMDLG32.OCX Missing?<\/h3>\n
If COMDLG32.OCX is missing from the Windows\\System32 or Windows\\SysWOW64 directory, you’ll receive the following error when running the RegSvr32.exe command-line:<\/p>\n
The module \"C:\\Windows\\SysWOW64\\comdlg32.ocx\" failed to load.\n\nMake sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files.\n\nThe specified module could not be found.<\/pre>\n
In that case, you’ll need to download the module and save it to C:\\Windows\\System32<\/code> (for Windows 64-bit computers) or Windows\\SysWOW64<\/code> folder (for Windows 32-bit computers).<\/p>\n
