How do I create an installation package for a VB6 program to run on Windows 8.1?

[judyalec]

I have been creating and running VB6 programs for many years. To reduce problems I have been compiling them and packaging them with the P&D Wizard under Windows 2000 in VirtualBox.
Up to Windows 7 this worked fine but with Windows 8.1 when I run setup.exe to try and install a program, I get the message
Cannot start the main setup program! (CreateProcess() returned error code 0x000000C1H)
I have tried installing from an XP created P&D Wizard setup with the same result.
Can anyone help me please.

I also have been installing programs for many years using the inbuilt setup routine within VB6.

I agree that things have worked relatively well until win8 when some installations worked without a hitch and some didn't. The problems have centred around the apparent failure to register of some the OCX files. Sometimes manual registration using the regsvr.exe has helped and sometimes that has failed.

Any comments?

Just a bit more info on the OCX problem.

After some research, it seems that the standard setup.exe calls the default regsvr during installation, which would be regsvr64 on a 64-bit machine, which cannot register a 32-bit file and so causes an error. However, these files can be registered manually in syswow64 by using regsvr32 from an admin command prompt.

This has worked perfectly on two 64-bit machines, but what I need to do now is to automate the process.
