My Sim Launcher won't open

I also have this problem, and it seems to be Origin-related.  I followed Crinrict's link from another thread.  I tried the factory reset and the advanced option.  The launcher failed to start without creating a new folder, and there were no leftover install files to remove, nor any mod folders or files within the program files or Origin directories.

In my case, it also occurred after an Origin update, although in my case it was a "repair install" that broke the game--I wanted to be sure that my game stayed as glitch-free as possible, so I ran the Repair Install through Origin.  The irony of a Repair Install breaking the game is not lost on me.

This appears to have something to do with Origin updates/repair installs, since we both had this problem today.  Probably, something in the files that Origin is checking for is corrupt.

As far as I can see, I've got two options:  Wait for Into the Future to come out, since I preordered, or reinstall and hope that fixes the problem.  Considering how long a reinstall will take for all expansions and several stuff packs (and if it is the Origin files, it won't even work), alternative suggestions are welcome!  I don't really want to use the workaround for this because I have content from the Sims Store, and can't manage/download that content without the launcher.
