Question

I’m trying to set up a new Windows Forms Application (C++/CLI) in Visual Studio 2010 on Windows 7. Every time I try to open up the Designer, it fails with this unhelpful error:

Exception from HRESULT: 0x8CE00001

If I debug Visual Studio and break on CLR exceptions, it actually throws this exception first:

A first chance exception of type ‘System.ArgumentException’ occurred in Microsoft.VisualStudio.Design.dll

Additional information: The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

This is with a clean, new project (File → New → Project… → Visual C++ → CLR → Windows Forms Application). After I create a new project, opening up the autogenerated Form1.h results in the error instead of the Designer. However, if I create a C# Windows Forms Application instead of C++/CLI, it works fine.

Any ideas on how I can solve this problem and open up the Designer? I’ve tried all of the following to no avail:

• Reinstalling VS 2010 SP1
• Running Windows Update, which installed two VS-related updates (“Update for Microsoft Visual Studio 2010 Service Pack 1 (KB2736182)” and “Update for Microsoft Visual Studio 2010 Tools for Office Runtime (KB2764593)”)
• Installing KB2635973, which fixes a similar-looking issue
• Rebooting after installing the above
• Turning off all DirectX debugging/validation settings in the DirectX Control Panel
• Uninstalling anything with “Microsoft SQL Server Compact” in its name via the “Program and Features” control panel

I’ve found a few similar threads online (one, two, three), but they’ve all been inconclusive or not worked for me. I’ve not yet tried fully reinstalling Visual Studio, but I may have to try that next.

After much nuking and reinstalling, I believe this to have been a problem with a Visual Studio Extension.

Completely uninstalling Visual Studio (even with VS2010_Uninstall-RTM.ENU.exe /full /netfx) and reinstalling it didn’t help. But, if I created a new Windows user, it worked fine for that user. Similarly, if I nuked my HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0 and HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0_Config registry keys (and their subkeys), it worked.

After painstakingly comparing my old registry (where it gave the error) with a fresh registry (where it worked) and reconciling them, the only differences that remained were related to a particular VS extension. Since I no longer need that extension, I don’t need its registry keys, so without them, the Designer is working as expected.
