Problem deploying Biztalk Application - Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

Question

Any idea why I would be getting this Access Denied Exception? I'm deploying a very basic Biztalk 2009 project from Visual Studio.

error DEPLOY: 
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

error DEPLOY:    at Microsoft.BizTalk.Gac.Fusion.IAssemblyCache.InstallAssembly(AssemblyCacheInstallFlag flags, String manifestFilePath, FusionInstallReference referenceData)
   at Microsoft.BizTalk.Gac.Gac.InstallAssembly(String assemblyPathname, Boolean force)
   at Microsoft.BizTalk.Deployment.BizTalkAssembly.GacInstall(String assemblyLocation)

Answer 1

Use Run As -> Administrator for Visual Studio. You must have Admin privileges to deploy BizTalk assemblies (since they deploy to the GAC).
