cakewalk sonar X1 is compatible with Windows 7.




Error 3 means "path not found". It's because the DLL or OCX is missing, or a dependency is missing. Most likely, the setup program was unable to write one of the files. This can be caused by having a file in use, or insufficient Windows permissions.


Method 1: Install the program in elevated mode and see if that helps.


Follow the step mentioned below:


 Right click on the .exe file of the program  and click on run as adminstrator.


Method 2:  Fix problems with programs that can't be installed or uninstalled:



Method 3:  Install the program in clean boot and see if that helps.
