I want to install gwt developer plugin for IE (I already installed it on chrome and firefox without any problem). When i want to install it for IE7 (on both vista with sp2 &
I had this issue too. In my case the error code was: 1612.
The problem's cause was, that after my windows user profile was broken, I renamed it and downloaded all my data from the server into the new user profile location.
To solve this issue I did the following steps:
* First I uninstalled the old GWT Dev Plugin for IE in Control Panel -> Add/Remove Software
* As the user profile was stored in a new location i manually had to specify the location of file gwt-dev-plugin-x86.msi in the new user profile
* Finally I opened http://gwt.google.com/samples/MissingPlugin/MissingPlugin.html in IE and installed the plugin again successfully
Hope it helps :=)
