Classic InTouch is often installed with both Development and Runtime features enabled. We've typically installed both features, even if it really is an InTouch runtime node only, and let the license determine how it's used. This causes a problematic upgrade with InTouch 2012. If you've installed both features, the installer program cannot tell whether the node is being used as a Runtime or Development, so it will upgrade both features.

Why does this matter? Because with InTouch 2012, a Development workstation includes not just InTouch, but also Wonderware Application Server and Microsoft SQL Server (for ArchestrA graphics development).

So when you upgrade an InTouch node, it will likely install InTouch, Application Server, and MS SQL Server Express.

This does not create a huge problem, but it does use additional hard drive space and runs some additional services. And it certainly is unnerving if you didn't expect it.

To avoid having the installer migrate your InTouch Runtime to a Development platform, you should first modify your existing InTouch installation and remove Development from the feature list.

In Control Panel / Add or Remove Programs, select Wonderware InTouch. Click 'Change'. In the subsequent Setup dialog box, select Modify, and then click Next.


Click InTouch Development, then select Entire feature will be unavailable. Then click Next and complete the install wizard.

You can now upgrade to Version 2012 and it will properly detect that this node is just an InTouch Runtime.
