Update to this thread, and PURELY a FYI for those directly affected i.e. SD games not starting on Win98SE due to Patin Couffin layer v12 and also v13. (4.5.7 uses v14 layer so this may not affect you).
(Support never answered the question at all by e-mail btw).
A file exists which I was TOLD is automatically installed in the VSO folder since Blindwrite 4.4 and later, called pcsetup.exe.
It was never installed here, and I've not been able to find anyone else so far who has this file either on Win98 OR WinXP! It is installed with Blindwrite 5 alpha (220.127.116.11) though.
To remove Patin Couffin do the following:
Start->Run then browse to the pcsetup.exe which will put the path in the CLI window. Type a space and add the following "/remove /removeatip" without the inverted commas. Click OK. Reboot.
Patin Couffin is now history (unless they have even more secrets hidden).
Monitoring what this file does with these CLI parameters is:
Deletes the files:
Deletes the registry entry:
HKEY_LOCAL_MACHINE\Software\VSO\Patin Couffin (Patin Couffin is removed)
So you don't actually need pcsetup.exe to achieve the same result.
What a game!
(To remove the Patin Couffin entry from the Control Panel delete the file patin.cpl from Windows\system)
