I have installed Morrowind in D:\Gog Games\Morrowind not in C:\Program Files or (x86) but find it does not launch at all. what happens is when I doubleclick the launch.exe windows says it goes into "basic" mode but just sits there on the desktop. I have to doubleclick numerous times for the game to launch at all. sometimes it just flashes the screen and does nothing. I have rebooted several times just to get it to launch once, it rarely does. I do not know if this has to do with disabling the UAC but have tried both disabling it and enabling it again but does not work. I am assuming something is messed up with windows since I disabled UAC but I do not know for certain.

Is it possible that there is a conflict with a previous installation of Morrowind?

Your description sounds like something went wrong with the installation - but don't worry about the installation folder or UAC.
Try uninstalling and reinstalling Morrowind. Ideally you should remove all traces of Morrowind from the registry after the deinstallation - but don't do it yourself if you are not familiar with editing the registry.

Before you do this you could make a final attempt: Don't use the desktop icon to start Morrowind, but go to the installation folder and double click Launch Morrowind there. I don't think it helps, but it can't do any harm to try.

this also happened with Vampire Masquerade Bloodlines CD-ROM installation, no this is the first time I have installed Morrowind but I did it from the GOG Galaxy installer. I will try downloading Morrowind from GOG and doing it manually. as for Vampire Masquerade(maybe a separate issue maybe not) I have attempted to run and install it twice don't know if it is something in that that affected Windows 7 or not but it seems some games, specifically ones made during the time period these two games were made, early 2000's that affects the way WIndows 7 handles them. I have no trouble running newer games nor do I with DOS Box, only games made during 2002-5(I think is when Morrowind and Vampire were made along with a handful of others.)
however, both Oblivion and Morrwind get the "stopped running" error when I exit and that has nothing to do with this issue related to startup except that it might be related to Morrowind's behavior in some way to this. Oblivion, of course was made much later has no problem launching doesn't relate to this except for the exit issue being the same as Morrowind. "stopped running" followed by my keyboard and mouse not working unless I go into task manager and exit there.

as for the in Morrowind folder launch, I have attempted to use the launcher there which brings up the menu to launch the game however, I have to double click it several times to get it to come up at all. this may or may not be related to the crash on exit. I do not think having to click it numerous times is very healthy for windows in the long run, but I am not an expert on how this affects windows but it maybe trying to run a previous instance of Morrowind when I attempt to doubleclick it again. this may relate to the "stopped running" error. but Oblivion does this even after I reboot and try running it. The Morrowind behavior is probably related to how windows handles Vampire Masquerade rather than Oblivion's exit problem, and the start up issue is the same. As with Morrowind, I must, again, double click it at least twice to get Vampire to run it runs after about two attempts but while does not crash on exit it may or may not be affecting WIndows behavior in handling other games ability to run as that was the first time this behavior occurred I don't know why it happened at all.
I used Revo uninstaller to uninstall Vampire and Steam's Oblivion, and Morrowind it did not find any trace registry entries with Morrowind. I found nothing using Glary utilities either. however have used Glary to clean my registry before and think maybe that is the cause of this behavior, don't know.

I have tried installing Morrowind again and when launching does nothing except go to Windows "basic" I go to the task manager find Morrowind Launcher*32 in processes but it does nothing but sit there. using 00 CPU and about 2300K memoryI cannot create a dunp file says "Operation could not be complete. Access denied. this is bordering on frustrating.

this problem seems to be related to rundll32.exe running along side. every program that utilizes this in the task manager refuses to run unless I dobuleclick it twice. in the case of Morrowind if I click it comes up with the menu but won't launch unless I go through this process again.

actually I found the solution but it is not recommended unless you know how to edit the registry as it involves going through and deleting all of the gameUX entries EXCPET for {xxxxx-xxxxx-ect} anything in that DO NOT delete. saying this in case other gamers have trouble running games that use rundll32.dll and want to shut it off.

Can't help you with that, sorry. I never used Win7, and never came across any gameux.dll-associated problems. But thanks for explaining the problem - it was interesting reading, and, who knows, it may prove useful information, should I run into such a problem myself.

It is a risk but worth it if you are careful. I honestly would be apprehensive about doing it again if I had to. but this site has the info on rundll32.exe problems. http://answers.microsoft.com/en-us/windows/forum/windows_7-gaming/older-games-causes-rundll32exe-to-open-and-100-cpu/2b15ee2f-b56b-e011-8dfc-68b599b31bf5

it seems that running games offline(I only do so with non muli-player games for security reasons) is a problem when old 32 bit games get stuck in Game Explorer, though these games do not use DRM at all, they get put in Game Explorer and that makes them "think" there is a problem. this is info I read, so I don't really know the reason. Getting plaecd into Games Explorer I assume done by ether GOG Galaxy or Steam Cliant or both(though Morrowind is not a Steam game) if you play online and never disconnect it is not going to be a problem. Probably why a lot of people are baffled when I bring it up on most forums across the web.

Morrowind and Oblivion CD-Rom both have the problem in the Windows Games Explorer if they get put there for some reason. If you ever do a fresh install of Windows I'd disable Games Explorer in Start Menu<Taskbar and Start Menu Properties<customisze have games never display(Unless your version of windows requires it be displayed). this only works on new installations of Windows 7 and maybe 8 and 10 but I have not used 8 or 10.

if you really want something to work(Like TES games) you have to hire a detective to ferret out all the MS skeletons. I found some in the last week I never knew existed. LOL.

Skeleton or strait jacket? :-) :-(
