Currently running Win 7 64 bit trying to run bd-rebuilder gives me this error Component MSCOMCTL.OCX or one of its dependencies not currently registered ...
Added MSCOMCTL.OCX to the System32 and registered it. Now giving me THe module "MSCOMCTL.OCX" may not compatible with the version of WIndows that you're running. Check if the module is compatible with an x86(32-bit) or x64(64-bit) version of regsvr32.exe.
You'll probably have to find the 64 bit version of it, if it exists.
On a 64-bit Windows the place of this OCX is c:\windows\SysWoW64
There is no 64 bit version of it and your old 32-bit application most probably need it. So copy it to SysWoW folder
