Can't install pltcl

I am currently trying to install pltcl on my Win32 8.0 version of PG, and am
receiving the incredibly generic message:

createlang: language installation failed: ERROR:  could not load library
"C:/Pro
gram Files/PostgreSQL/8.0/lib/pltcl.dll": dynamic load error

The postgres user has read permissions on the tcl bin directory. I also ran
depends.exe on the pltcl dll, and everything appeared to checkout. Where do
I go from here in trying to determine what is wrong?

Thanks,
Steve
