I had some time over the weekend so I was able to attempt to upgrade my Nero installation, expecting problems because I have had upgrade problems before.
I have a full licensed version and I was running all parts of the previous 220.127.116.11 and as far as could tell it was all working, well all the bits loaded.
I first opted for the ProductSetup route. All seemed to work OK and the update downloaded and because of InCD running I was quite rightly prompted to restart which shutdown InCD to continue with the install.
Once almost completed I got a "Unable to Access Shell Manager" error which rendered the remainder of the upgrade useless and nothing would work or even start.
Uninstalled via the various Nero Cleantools.
Reinstalled 18.104.22.168 without InCD and tried the ProductSetup upgrade path - this time it worked OK. The only complaint I have at this stage is that I was prompted, yet again, to choose the Audio, Video, etc, file associations. What a pain that is.............
Then went to reinstall InCD as a seperate installation via Add/Remove programs 'modify' option.
InCD would not install because I had an updated installation (22.214.171.124b) which was located in the 'Nero Web' folder and the Nero Web folder did not contain InCD because it was not required to be downloaded when I upgraded.
Therefore the only route left open was to use Cleantools again and download the whole package and install from scratch.
I have now finished my install/upgrade testing and I am now not running InCD, MediaHome or Snapshot as I already have other apps that cover those functions quite well. InCD has been replaced in my case by memory sticks which I use for moving large files around that used to be the job of CDRW's via InCD.
All in all not really impressed considering I used to get a regular flawless upgrade to my Nero 5.5 with no issues at all.
