Finding the last install directory

Hi all,

this is my first post, so I apologise if my search skills missed the answer to this question.

I want to be able to pick up the install directory of another install. This covers 2 scenarios:

1. To update an installation I created, so it's possible to "write" something to the registry myself every time if necessary.

2. To find the install directory of another product that I didn't make the install for.

Any help is greatly appreciated.

You can read registry entries using ReadRegStr and Write them using WriteRegStr.
