Thanks, Gerhard.
I think that the issue would have been caused by your attempt to copy the v3 installation en masse onto the new computer. One can't simply copy the installed Hauptwerk application (or most other installed applications) directly from one computer to another -- its installer needs to be used to install it on the new computer, otherwise components are likely to be missed (or configured incorrectly for the new computer) and/or file/folder permissions are likely to end up incorrect, potentially preventing Hauptwerk and/or its installer from being able to work properly.
(Also, there's no benefit in installing an older version in order to upgrade to a new one -- the new version can just be installed directly.)
Please try the following:
- If you're currently able to get Hauptwerk to launch at all, and if you have any settings/combinations/etc. in Hauptwerk that you want to keep then use '
File | Backup ...' within Hauptwerk to back them up. (Alternatively, if you already have a suitable recent backup made using '
File | Backup ...' within Hauptwerk then that could be used instead of making a new one.)
- Exit Hauptwerk if it's running.
- Use Windows Explorer to make sure that any and all of the following folders that exist are completely deleted (entering your computer password if so prompted):
C:\Program Files\Hauptwerk Virtual Pipe Organ\
C:\Program Files\Hauptwerk Virtual Pipe Organ VST Link Plug-In\
C:\Program Files\Hauptwerk\
C:\Program Files\Zero G Registry\
C:\Program Files (x86)\Hauptwerk Virtual Pipe Organ\
C:\Program Files (x86)\Hauptwerk Virtual Pipe Organ VST Link Plug-In\
C:\Program Files (x86)\Hauptwerk\
C:\Program Files (x86)\Zero G Registry\
C:\Hauptwerk\
- Reboot for good measure.
- Run the full Hauptwerk v4.2.1 installer to re-install Hauptwerk from clean (
http://www.downloadhauptwerk.com/ ).
- Also make sure that the latest version of the Hauptwerk USB key driver is installed (
http://www.downloadhauptwerk.com/ ). (It doesn't to re-install it if unsure.)
- Reboot.
- Launch Hauptwerk. It should now launch properly.
- If you had previously made a backup of your settings then use '
File | Restore ...' in Hauptwerk to restore it.
- Use '
File | Install ...' to re-install your organs from their original installation media or downloads.
