Cannot register DLL on Server 2012

Cannot register DLL on Server 2012

We have an old classic ASP website that I'm trying to host on a new Server
2012 box. It uses a DLL developed in house on VB6.
I copied the installer file over and it error's out. I try to register the
DLL manually using "regsvr32 pathToDll\theDll.dll" and it comes back with
error 0x80004005. Google suggests that I should run the command from an
elevated command prompt. So I do and I get the same error. I've also tried
running the same command from the SYSWOW64 directory and I get the same
error.
Through Googling, I also find that it could be from missing dependencies.
I used Dependency Walker and sure enough it was missing a few things. So I
found out I had to install the VB6 runtime files, and enable a few
features and all the dependencies are resolved. So I tried reregistering
the DLL and it still gives the same error.
Any ideas? I know it's a 32 bit dll on a 64 bit machine but it should at
least register.
