Edmap Cdviewer Runtime Error 732 Reddit

EDMAP CDViewer Runtime Error 732 Reddit has become a common search phrase for users experiencing technical difficulties with this mapping and data visualization tool. Runtime Error 732 is not unique to EDMAP CDViewer, but its appearance in this software has frustrated many users who turn to forums like Reddit for troubleshooting tips. This article breaks down what Runtime Error 732 means, why it occurs in the EDMAP CDViewer environment, and practical solutions users have shared and tested.

What is EDMAP CDViewer?

EDMAP CDViewer is a compact geographic data viewer used to display maps and spatial datasets stored on physical media like CDs or DVDs. It is commonly distributed with state or federal geological data and widely used in educational and research settings.

The tool is lightweight but heavily reliant on Windows components such as:

• Visual Basic 6 runtime libraries
• COM-based data controls
• System-level components like MSCOMCTL.OCX and MSINET.OCX

Its legacy architecture is a double-edged sword—great for older systems, but problematic on modern machines.

Understanding Runtime Error 732

Error Message:

“Run-time error ‘732’: Unable to create ActiveX component”

What It Means:

Runtime Error 732 indicates that the software failed to instantiate an ActiveX component during launch or data loading. This usually points to:

• Missing system files
• Improperly registered ActiveX controls
• Insufficient system privileges
• Incompatibility with newer operating systems (e.g., Windows 10 or 11)

Common Reddit Discussions

On Reddit, particularly in subreddits like r/techsupport and r/GIS, users have identified the following scenarios triggering Error 732:

• Attempting to run EDMAP CDViewer on 64-bit Windows without dependencies
• Launching the program from a mounted ISO image without admin rights
• Corrupted OCX files
• Running on machines lacking legacy VB6 runtime libraries

Some users have even provided step-by-step remedies based on their trials, which we’ll summarize below.

How to Fix EDMAP CDViewer Runtime Error 732

1. Re-register the OCX Files

The most common fix is re-registering ActiveX controls like MSCOMCTL.OCX or MSINET.OCX. Use Command Prompt as Administrator:

regsvr32 MSCOMCTL.OCX

If successful, you’ll see a confirmation dialog. You may also need to register multiple OCX files depending on the installation.

2. Install VB6 Runtime Libraries

Microsoft still hosts the Visual Basic 6.0 runtime package. Download and install the following:

• VB6 SP6 Runtime
• Microsoft Visual Basic Common Controls

Reboot your system after installation.

3. Run as Administrator

Right-click on the EDMAP CDViewer executable and choose “Run as administrator.” Lack of elevated privileges can block system-level file access, especially when accessing ActiveX components.

4. Use Compatibility Mode

Navigate to:

Right-click > Properties > Compatibility Tab

Check “Run this program in compatibility mode” and choose Windows XP (Service Pack 3). This has worked for many users on Reddit.

5. Copy the Program Locally

If you’re running EDMAP CDViewer from a CD or mounted ISO, copy the entire directory to your local hard drive. Then retry the execution with administrator rights.

6. Check 32-bit vs 64-bit System Architecture

The CDViewer is a 32-bit program. Running it on a 64-bit system can sometimes block access to certain 32-bit dependencies. Solutions include:

• Using a 32-bit VM (like Windows XP via VirtualBox)
• Running the app in Windows Compatibility Troubleshooter

Additional Suggestions from Reddit Users

• Use Dependency Walker (depends.exe): This tool analyzes executable files for missing DLLs or OCXs. You can quickly identify what component is triggering Error 732.
• Disable UAC (User Account Control): Temporarily lowering UAC settings may allow the program to register its components, though it should be re-enabled for safety afterward.
• Install in Safe Mode: This avoids interference from background processes or antivirus software that may block registration of OCX components.

When Nothing Works: Virtual Machines

If all else fails, Redditors often suggest setting up a lightweight Windows XP virtual machine using:

• VirtualBox
• VMware Workstation Player

In this environment, the EDMAP CDViewer usually installs and runs without errors. It’s a reliable workaround, especially when working with older geological data sets.

Preventative Tips

To avoid future errors like Runtime Error 732:

• Always install legacy software with admin rights
• Back up required OCX/DLL files
• Document what version of Windows your tools are compatible with
• Avoid installing critical components from unknown sources

Conclusion

The issue described by edmap cdviewer runtime error 732 reddit stems from the challenges of running legacy software on modern systems. With proper knowledge of OCX registration, system architecture, and compatibility tricks, users can often overcome these barriers. Reddit has proven to be a goldmine of firsthand experiences, offering valuable community-based fixes for otherwise obscure problems.

While EDMAP CDViewer remains a useful tool for certain fields, the underlying technology is outdated. Users should explore alternatives or maintain virtual legacy environments to ensure continued functionality. If you’re dealing with Runtime Error 732, don’t give up—community forums, technical diligence, and step-by-step troubleshooting can usually provide a way forward.
