Unable to Install Soma ! Error message

[Romulator]

VCOMP100.dll is a Windows Visual C++ Redistributables package. They may have become corrupted or you just haven't installed it yet.

You must have a 64-bit Operating System to play SOMA. You can make sure you do by going to your C:\ Drive and making sure you can see Program Files and a Program Files (x86) directory there.

Assuming you do, go to Problem A8 of the troubleshooting guide and install the software from those links.

Try to run SOMA after that and see what happens.
