I run my custom application for XPression on a new desktop which was installed a developer. The application work well on my studio and bluebox turnkey systems. But it prompts an error message on the new desktop as below:

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll

Additional information: Retrieving the COM class factory for component with CLSID {313CF0C8-2F04-4A83-839E-075D70E89FE7} failed due to the following error: 800702e4 The requested operation requires elevation. (Exception from HRESULT: 0x800702E4).

Moreover, I created a new C# project, and set the target platform to x86. Same error on "[I]xpEngine engine = new xpEngine();[/I]".

I have tried "XPression (register COM API)" but useless. How can I fix it?

Thanks!

Hi Nero,

I've had a similar problem before. I've built an application on my laptop where it was working and when I passed to another PC, I got the same error.

It took me a night to find out but it had to do with the references to the XPression COM-library.

On your new pc, try to remove the reference from your References-tab in the Project Solution.

And then add it again but use the local library which can be found on C:Program Files (x86)XPressionStudionet

Then try running your application again and see if that works.

Have you already tried running XPression and the application by right clicking on it and choosing "Run as Administrator"?

I've never had to do this on Windows 7 Professional as long as my account was an Administrator, but I've needed to do it when running Win 7 Home Premium even when using an Administrator account. If running the app inside visual studio, you would need to start Visual Studio as an Administrator as well.

Hi Kenneth,

Same error although I add the "xpression.net.dll" as my local reference, so I tried Brian suggestion.

Brian,

It works! The problem seems my Visual Studio is not running under administrator permission. Thanks a lot!
