The only time I've seen a need to reconfigure the IDE was for DCOM for client/server applications and I don't think that applies here.
Nor am I convinced that you got the error regarding crystal.ocx when you were registering ieframe.dll etc - these are related to Internet Explorer.
My advice would be to install/reinstall Crystal Reports from your VB6 install CDs (Disk 3 I think) - from memory I don't think it is included by default, but if it was then your installation is corrupt and needs to be fixed.
If you are still having problems with ieframe.dll etc then you should uninstall/reinstall whichever version of Internet Explorer you are using - there will be instructions on the MSDN website appropriate to your version.
As an aside, frequently errors are reported when using regsrv32.exe if your account does not have administrative rights on the machine... try again using an appropriate logon.
Another common problem is that one of the dll's that the item depends upon has not been registered ... Depends.exe can find this out for you - again it's available from MSDN and is free.
Also be aware that the VB6 development environment is no longer supported - it will work on Windows 7 and below, but often not without some issues. Consider updating to a more robust development tool such as Visual Studio Express - which is free to
