Installation procedure for removing AEM Designer version previous to 6.5.15

[koolForms]

I have a client that needs to upgrade their staff from AEM Designer 6.5.0 to any version more current that 6.5.15 (We are targeting 6.5.18)

I am looking for some documentation on the Adobe approved process to remove previous versions, and the install of versions from 6.5.15 or higher.

At this time we have 2-3 machines that an attempt to upgrade was made and the install failed. Now they cannot uninstall or re-install without receiving and error.

The basic procedure they are following:

1. Uninstall AEM Designer 6.5.0.

2. Install AEM Designer 6.5.15. - This is where they are getting stuck.

3. Install the upgrade to 6.5.18.

I believe that all necessary C language updates are in place.

There is no Workbench install.

Thanks for any help you can give me.

Thank you for the link.

Unfortunately, the prescribed solution does not work.

This has happened before on this exact machine and I had to re-image. Can someone from Adobe who is watching comment on a solution?
