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 & windows server 2008 with sp2), it says that plugin installed sucessfully, but it does not work & nothing adds under add-ons section.
I upgraded my ie to latest 8 version & even installed google optimized version of IE8, but it couldn’t help me.
Any idea ?

    I had the exact same problem on IE8 windows XP, where it said it installed successfully. But it still showed the install message in the browser (and not the actual application).

    I figured out why this was not working for me, and the root cause was that the network administration login routine apparently had created two profiles for me:

    C:\Documents and Settings\g43899 (outdated profile location) and

    C:\Documents and Settings\g43899.ND60A600 (new profile location)

    Before I explain further, have a look at the suggestions on the GWT defect list, issue 4358:

    1. Is the following registry key installed:
      HKEY_CLASSES_ROOT\CLSID{1D6156B6-002B-49E7-B5CA-C138FB843B4E}?
      If so, what are its subkeys and
      values?
    2. What happens when you run “regsvr32.exe oophm.dll”? Can you try
      running “regsvr32.exe /u oophm.dll”
      and then “regsvr32.exe oophm.dll”?

    On my machine, the registry key did not exist. Furthermore, I got an alertbox error when running command regsvr32.exe oophm.dll:

    LoadLibrary("oophm.dll") failed - The specified module could not be found.

    I was able to locate the DLL file to the first folder at

    C:\Documents and Settings\g43899\Application Data\Google\Developer Plugin\IE\oophm.dll

    But as this location was related to the outdated profile, I did the following

    1. Moved folder from Application Data\Google\Developer Plugin into the new profile location.
    2. Ran regsvr32.exe "%APPDATA%\Google\Developer Plugin\IE\oophm.dll"

    After that command, I could actually see the registry key HKEY_CLASSES_ROOT\CLSID\{1D6156B6-002B-49E7-B5CA-C138FB843B4E}. Now everything suddently worked. Hope this can help you.

    I am adding the full contents of ´HKEY_CLASSES_ROOT\CLSID{1D6156B6-002B-49E7-B5CA-C138FB843B4E}` in case you need it.
