Troublshooting guide for GWT plugin

When I try to use the GWT dev mode plugin for ie 8 on Windows Vista I continually see the prompt to install the plugin.

After running the plugin I still always see this page. Does anybody know of how to troubleshoot some开发者_运维问答thing like this?

See this : Can't install gwt developer plugin for IE 7 or 8

Manually running regsvr32.exe oophm.dll fixed the issue for me.

What GWT version are you running?

Try to install the plugin from here:
