RMXP won't open?!

[Tenoukii 0]

So, as the title states... RMXP refuses to open.

I have Windows 7 64bit

It used to open fine without running as administrator or troubleshooting compatibilty, bit now not even that works!

I tried re-installing, re-installing win-7, troubleshooting compatability, running as administrator, and everything else I can't think of right now.

I've got so fed up with it that I just left it uninstalled now.

Any help/sugestions would be appriciated.

Thanks (:

Here is a 100% sure way to do this. I have personally done it at least 20 times, and it has worked every time. I have Windows 7 x64, so I can say this with certainty. I see all sorts of complicated ways of people doing this, and they still have problems.

1. Make sure you have RMXP uninstalled, if want to clear any license data, open your registry editor ("regedit" in the Start menu search box) and erase these keys: "HKEY_CURRENT_USER\Software\Protexis" and "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Protexis"
   
2. Get your RMXP installer. I suggest an older one. Enterbrain changed the authentication process. Here is a link to one of the older installers: http://dl.dropbox.com/u/20787370/RMXP/RPG%20Maker%20XP.zip
   
3. BEFORE running it, right-click the installer ("SetupMenu.exe"), and got to Properties -> Compatibility and check "Run this program in compatibility mode for:"
   
4. Select "Windows XP (Service Pack 2)" from the dropdown. Service Pack 3 works as well, I have used both, but number 2 is the common convention for some reason.
   
5. Run the installer as admin, install the RTP, and then the program.
   
6. Do the same with the program once it is installed before you run it, then run it as admin.
   
7. Enter you license information.
   
8. Go back to the properties of RPGXP.exe, and now uncheck the compatibility box. This makes it so that you don't need to run as admin every time you use it. The admin and compatibility stuff is only for gathering and creating the license information, once its in there, your good to go.
   
9. If you still have problems, or anyone doubts this method, I will make a video demonstration showing me doing it and running RMXP without admin rights on a x64 bit version of Windows 7.
