It worked with a workaround. I copied the TTSRES.dll 64 Bit File in the
[<font]Program Files (x86)\Steam\steamapps\common\Cakewalk\SONAR\ [<font]Folder.
[<font]Then i installed the Mod. After that i copied the TTSRES.dll File Back into the 64 Bit Folder
[<font]
[<font]Program Files (x86)\Steam\steamapps\common\Cakewalk\x64\SONAR\ [<font][<font]and startet 64 Bit Sonar.
[<font][<font]It worked. It would be cool when this would be fixed. Thanks ;)
