Thanks everyone, so re my last post 11...

Q1: To install from this ISO:
Is it OK to just right-click this ISO file (in Windows Explorer) and then click on Mount, and then double-click its Setup.exe

Q2: Also: Afterwards, do I still need to paste the VB6_IDE_Shims.sdb & the Install_Shims.cmd files
into folder: C:\Program Files (x86)\Microsoft Visual Studio\VB98 folder.
Then do I simply drag the sdb-file onto the cmd-file ?

Many thanks
