the answer from tc support:
Thank you for contacting TC Group Support.
Please try a full uninstall:
- backup your presets
- run the uninstaller
- make sure to delete the following files (if present):
Windows
Driver:
\Documents and Settings\All Users\Application Data\TC Electronic\PowerCore
\Program Files\TC Electronic\PowerCore
\Windows\System32\PCore.bin
\Windows\System32\PCore.cpl
\Windows\System32\PCore.dll
\Windows\System32\PCore.exe
\Windows\System32\pcore_co.dll
\Windows\System32\PcoreMsg.exe
\Windows\System32\drivers\PCore.sys
\Windows\inf\oem??.inf - These files come from all Windows driver installations, they must be opened in a text editor to find out which ones belong to PowerCore.
Plug-Ins:
\Program Files\TC Electronic\PluginName*
\Program Files\TC Helicon\PluginName*
\Program Files\Tube-Tech\CL 1B
\Program Files\Steinberg\VstPlugins\PowerCore
\Windows\System32\AmpRoomDSP_Lib44.dll
\Windows\System32\ AmpRoomDSP_Lib48.dll
\Windows\System32\ AmpRoomDSP_Lib88.dll

My Documents\Access Music\Virus Powercore
My Documents\Access Music\Virus Powercore
My Documents\TC Electronic\PluginName*
My Documents\TC Helicon\PluginName*
My Documents\Tube-Tech\CL 1B done on users’ own risk
\Documents and Settings\MyUserName\Application Data\TC Electronic\PowerCore
\Documents and Settings\MyUserName\Application Data\TC Electronic\PowerCore Prefs.xml
In these folders the user presets are stored, so deleting must be done on users’ own risk
Registry Entries:
HKEY_LOCAL_MACHINE\SOFTWARE\TC Electronic\PowerCore
HKEY_CURRENT_USER\Software\TC Works\POWERCORE
HKEY_CURRENT_USER\Software\TC Works\POWERCORE
There are various more entries automatically created by Windows during new device installation. Removing those is not recommended and must be done on users’ own risk. To do so, the complete registry should be searched for entries and keys named “PowerCore” and “PCore”.
- reboot
- install the new version (

- reboot
I hope this information has been helpful. If you should have any additional questions, please feel free to update this incident and I will be happy to assist you further.
