gwt developer tools IE8 plugin install problem on Windows 7

Today I started testing a gwt application on a new notebook with Windows 7. Testing with Firefox went OK, then I started it in IE8. The "Development Mode requires the Google Web Toolkit Developer Plugin" comes up, fine, click on Download. A moment (and a download) later, an IE security warning window comes up ("Do you want to run this software?"), click Run. BTW, I started IE as Administrator...

Then a nice progress bar is displayed, with 开发者_StackOverflowan "Initializing..." the text above, and it stays stuck forever.

Any ideas?

I had same issue, I think the installer isn't registering the plugin dll correctly. You can do this manually in a command prompt via:

regsvr32.exe "C:\Users\<your user name>\AppData\Local\Google\Google Web Toolkit\Developer Plugin\IE\oophm.dll"

This is based on a post on the GWT groups.
