HWPROJ Troubleshooting


Common Problems Opening HWPROJ Files

Microsoft Visual Basic Removed

Double-clicking your HWPROJ file prompts the message "%%os%% Can't Open HWPROJ File". If so, it typically means that you don't have Microsoft Visual Basic installed for %%os%%. You won't be able to double-click to open your HWPROJ because your OS doesn't know what to do with it.


Tip: When you have another program installed that you know will open your HWPROJ, you can select it from the other programs listed (see "Show Apps").


Outdated Microsoft Visual Basic

Occasionally, you might have an outdated version of Microsoft Visual Basic installed that's incompatible with your Visual Studio .NET Help Project type. Installing the latest version of Microsoft Visual Basic from Microsoft Corporation is recommended. This issue mainly occurs when your Visual Studio .NET Help Project file was created by a newer version of Microsoft Visual Basic than you have on your PC.


Tip: Find clues on the correct software version by right-clicking your HWPROJ file and clicking "Properties".


Conclusion: The majority of HWPROJ file opening issues are due to not having the correct Microsoft Visual Basic version installed.
