I'm running win7 x64. Installed the new x64 S3D finally. Went to start it, and got an error for a missing .dll file. My computer is mostly up to date, have the latest c++ redistributables and all that. After going through some runaround I got it working finally, but I had to find about 20 .dll files...
Here's a list of .dll files that my computer did not have, although my antivirus software did have them in it's install folder, so I was able to just copy and paste them into the S3D installation folder. In case I'm not the only one to run into this issue, hope this helps.
