I have solidworks files I cannot access on a older version, and managed to lose a 2005 published vcomp100.dll

This is keeping solidworks from starting.  

I will likely need to edit the register and insert a newer version of the file since Microsoft doesn't support downloads on the older 2005 and 2010 editions. Like some help if anyone knows how that will go.
