While waiting for a reply for ideas here, I had decided to try something. I ran regedit as administrator, navigated to the HKEY_CLASSES_ROOT\TypeLib Key and then did a search for "MSCOMCTL.OCX"... I deleted EVERY key that referenced this .ocx file.
After searching the entire registry, deleting what I found, I ran command prompt as administrator. I then navigated to C:\Windows\SysWOW64 and typed the following commands:
regsvr32 MSCOMCTL.OCX
regtlib msdatsrc.tlb
Upon registering these two files again, everything is WORKING! I scoured the web for HOURS looking for this solution to no avail. It just so happens I fixed it myself after posting a question here :( Even though Visual Studio 6 is outdated, hopefully this may still help others!
