Just updated my computer from windows 10 to 11. ACL 16 Deluxe working fine before but now I get an error -6 ? Cannot find any windows compatibility settings to make it work. Is that the end of my software now we've reached Win11 ?
Assuming you mean Magix Audio Cleaning Lab 16 then this is a very old version from 2010 and is not compatible with Windows 11.
Re-installing would be pointless as the product uses a discontinued P2- serial number and will no longer register/activate.
The current version of the program is Sound Forge Audio Cleaning Lab 4.
I would suggest you download the trial version to test and if it is OK for what you need then you should qualify for the Upgrade price however when I checked the price buying the program using New purchase option is cheaper than the Upgrade price !
Once purchased you have only need to enter the new serial number into the trial version, there would be no need to uninstall/re-install.
