While this has been answered below in chaospearl's post, and while the thread itself is aging a bit, I thought I'd add a little tip to make this simple for those folks running into similar problems. The issue here is that some tools were designed to run on Winx86 (32-bit) OS platforms, and are therefore not familiar with the Winx64 registry structure. On Winx64, when you install Oblivion or Morrowind, the Bethesda Softworks registry entry goes into the [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node] path rather than the expected [HKEY_LOCAL_MACHINE\SOFTWARE] path. The easiest way to fix this without breaking anything is to do the following... Open Regedit (it's scary, but as long as you make only these changes, you'll be ok).Go to the [HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ Bethesda Softworks] path and click on it to highlight it.Right click on the Bethesda Softworks path on the left and select EXPORT.Choose any location to save the file that you will remember and name it something like "bethsoft.reg".Open the folder where you saved the file, right click on the file (in this case "bethsoft.reg"), and open it with your preferred editor (I like Notepad++).From the drop-down list of the editor, select the "Replace" option (in Notepad++ it's SEARCH-->REPLACE).In the FIND WHAT: box, type "Wow6432node\" with the backslash but without the quotesIn the REPALCE WITH: box, leave it blank.Hit REPLACE ALL. It should tell you something like 39 items replaced (if you have both Oblivion and Morrowind installed).Save the file, and exit the editor.Now double-click the "bethsoft.reg" file, and it will ask you to confirm that you want to import it into the Registry. Say yes, obviously. When done, you should now have an exact duplicate of the Bethesda Softworks path from the [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node] path in [HKEY_LOCAL_MACHINE\SOFTWARE] path. This won't hurt anything to have duplicate entries in the different locations, but I'm not at all certain that various registry cleaner programs won't flag one or the other and "clean" it out. If this happens, if you saved your "bethsoft.reg" file, just double-click it again to reapply the changes to the Registry. After I did these steps, TES4Gecko worked fine for me. I've attached "Bethsoft.reg.txt" as an example of an edited version of the registry path ready to be applied, but your install paths may be different. If you installed Oblivion to "C:\Games\Bethesda Softworks\Oblivion", then you can just remove the ".txt" extention at the end of this file and use it. However, many folks are paranoid about applying reg hacks from unvetted sources (with good reason); so I won't be offended if you choose not to use it. :wink: Regards, -RMWChaos
