Ok, so, I got the multi part V60 data files and the v61 installer, extracted out the multi files to F:\Temp\Morroblivion , dropped the exe into the same folder as the 00 Core , 01 Better Map, etc directory, and ran it. It asked for the Morrowind and Oblivion folders so I pointed it to F:\Program Files\Steam\SteamApps\Common\Morrowind and F:\Program Files\Steam\SteamApps\Common\Oblivion folders respectively, and it said it was ready to install, clicked Install and it came back in less than a second as done. I peek in the Oblivion data folder and I only see Morroblivion_op.esm but not the esp, not the optional esps, not the bsas, but the folders (video, distantlod, etc) did copy over. Tried twice and it failed both times. Should I manually install the rest or ...?
Installer did everything it
Installer did everything it was supposed to - installed the master file.
The rest is installed manually or (preferably) via Wrye Bash.
... Right, missed a step
... Right, missed a step somewhere. >.< Ok, downloaded 7zip (I use WinRar to extract 7zips so...), compressed the files with the following settings. Archive format: 7z, Compression: Normal, Compression Method: LZMA, Directory Size: 64 MB, Word Size: 273, Solid Block Size: 4GB. and... Nope, still only copies over the Morrowind_ob.esm and directories but not the Morrowind_ob.esp, bsas, optional ESPs, etc.
Are you using Wrye Bash
Are you using Wrye Bash

Did you use 7z to
Did you use 7z to Re_Compress the Extracted files Back to Morroblivion_v60_Complete.7z
then Shift the 2gig file to where WB needs it to Read it..
Install only Creates ( Morrowind_ob.esm) if using WB it should read the Rest of the (.esp) in the 2gig Archive..
If you Did not Re_Compress the Files after running (Morroblivion_v60_Complete.patr01.exe) then you only Need to Cut All the files and Directorys Out of the ( 00 Core\Data ) Directory and Paste them into your Oblivion\Data Directory and say YES to Overwrite ALL..
then Do the Same with The Directorys for the Files you want to Run
