I really need some help.
I have already had to scrap one test server due to a corrupt LANDesk uninstall and I really don't want to have to ask the our Infrastructure team to rebuild again.
I have had a lot of issues lately when uninstalling and reinstalling 2 different versions of the LANDesk client. I am setting up a new test environment and installed the latest version of LANDesk 2016.2. I then removed this version and installed the current version we have on our live environment LANDesk 7.8 to go through and document the upgrade process from one version to another as I am aware that there is a part of the upgrade that migrates RSS Generator and Web applications. Here is what happened:
This was a brand new server built for testing and the install of LANDesk 2016.2 went smoothly.
I decided to remove 2016.2 - the uninstall reported 'Successful'. I then installed LANDesk 7.8 and this installation reported 'Successful'. After the install the Configuration Center login page launched but an error appeared after the installation:
System.InvalidOperationException: Instance validation error: 'Framework' is not a valid value for ComponentName.
I had a look on your site to see if I could find any information on this error but didn't find any. I then decided that I could live with not upgrading from one version to the other on this occasion as I knew this went smoothly when I attempted on the last server. So I removed LANDesk 7.8 and the uninstall process reported again as 'Successful'.
However, now when I try to install LANDesk 2016.2 it gets stuck at this "Removing Configuration Centre 'UninstallString' value from registry. I have attached the log if it helps.
The thing is it has midway installed the application and the only options are to Cancel or Try again - Try again fails but when you choose Cancel the setup closes but it does not rollback any changes and you are left with a partial install on your system and when you attempt to run the setup again it pick up where it left off - at the error message above.
It seems the uninstall of LANDesk doesn't clean up properly and leaves behind traces of previous installations and when a new installation hits an error it doesnt rollback the changes.
Is there a cleanup tool available or a guided manual uninstall procedure??
Any help would be greatly appreciated!
