Package failed to load “Visual Studio HTM Editor Package” in VS 2010

Hi, I installed Visual Studio 2010 on my machine with Windows Vista Ultimate 32bit, in which I already had installed VS Web Developer Express 2010 and Visual Studio 2008 Pro.

From that moment on, I could not work with Intellisense and HTML File inside both VS2010 and VSWDE 2010.

During first start I received an error of Package “Visual Studio HTM Editor Package” {1B437D20-F8FE-11D2-A6AE-00104BCC7269} not correctly installed.

This is the entry of the log file:

I tried with devenv /setup but it asks for higher privileges (??? I’m the Admin), I tried to reset settings as said here (http://blogs.msdn.com/b/webdevtools/archive/2009/10/23/visual-studio-2010-beta-2-intellisense-issue-in-javascript-html.aspx) but nothing
changed.

Trying now to uninstall and reinstall everything again.

Any piece of hint?

Hello,You may try following steps to see if they help:a)     Try to run devenv /ResetSettings, devenv /setup and devenv.exe /InstallVSTemplates (in command prompt) to eliminate the related potential settings problem.(Do remember to redirect the path for VS2010)b)     Try disabling Add-ins (e.g. “Tools” | “Add-in Manager”) or run “devenv.exe /SafeMode”.This can eliminate the possibility that third party Add-ins or packages are causing problems. (For more detailed
