Error Application unable to start correctly OXC000007B click to close when launching

System restore I tried first, and it worked, Origin works again, and other games run.  Opens super slow though, I will try the registration

mmm I said those to try to get the "broken" ones to work... not sure what we gained here but I wish you the best of luck and it fixes it.

The way my brain works it comes out weird and confusing sometimes I guess ☹️

hmmm , that's interesting, when I try, it gives me the following:  The module "mfc100u.dll" may not be compatible with the version of Windows that you are running. Check if the module is compatible with an x86 (32bit) or x64 (64 bit) version of regsvr32.exe

This is the chat transcript that suggested certain .dll - BUT those were not located at the link the Origin guy suggested.

Subrat: the issue seems to be related to your .dlls that AC4 tries to use when running.

Try the following steps -- 

1. Replace these files - mfc100.dll, mfc100u.dll, msvcr100.dll, msvcp100.dll and msvcr100_clr0400.dll

They can be found at http://www.microsoft.com/en-us/download/details.aspx?id...

Please save these files to any location on your PC;

2. Please reboot your computer in Safe Mode
3. Access C:\Windows\System32;
4. Locate the 5 files you have downloaded and extracted;
5. Next, copy all those files to C:\Windows\System32 replacing the current ones;
6. Reboot in Normal Mode

okay, I've copied my originals into a separate folder so I won't have to worry about that again

 Interesting thing I noticed, my files for  two of those .dll are newer than the replacements at that link, so I tried to register those two new ones, I got the following error "The module "msvcr100.dll" was loaded but the entry point DIIRegisterServer was not found. Make sure that "msvcr100.dll" is a valid DLL or OXC file and then try again."

Ever seen this error?

Is reinstalling windows out of the question?  You can shrink your current HD's partition, and install a second install of Windows... that way you won't lose anything.

I think we need to stop dude because I'm going to ruin your computer lol... but here it is anyways.

Trying to replace it or override any registration with an older version could corrupt the rest of Windows.

1. c:\system32 and fine file "Regsvr32.exe"
2. Right click and click in properties and go to security tab and click in advanced button.
3. Click in owner tab and click edit and select administrators and click ok.
4. Click in permissions
5. Click in change permissions.
6. Choose administrators and click edit and put tick on full control and click ok.
7. choose SYSTEM and edit and put tick on full control and click ok and click in other dialog box which are opened.
8. Register the DLL

*edit*  Is this windows 8?  Heck we could just a "Refresh" PC... not the "Wipe Clean" option but just the Refresh... I've done that on Surfaces with great success... both the Refresh and the Wipe Clean.

Here's a possible fix,  with link to videos (I figured this out on my own,  so maybe it will help - i now have the game up and running):
