Waves Central 13 is unsupported on Windows 7.

This would not be a problem if every previous version did not insist on upgrading automatically and immediately to version 13 and fail to run saying permissions are wrong.

Looking in the log files it seems a DLL: 'api-ms-win-core-path-l1-1-0.dll' is unavailable to python39. This is because it doesn't ship with Windows 7. By a happy happenstance nalexandru on github has produced a backward compatible version of this library in order to run a particular version of Blender on Windows 7.

Pop the DLL in the your %WINDIR%\System32 folder and hey-presto, you are good to go.

You can then install the version of the plugins you require (V10 plugins certainly work) by going to "Install Products" and "All Products" and filtering on Version 10.

This took me two days to figure out so buy me a half beer on the link on the right if this has helped you.

A binary version of the DLL is attached below.

Thanks.
Matt.

 Update: Version 11 plugins seem to work (The few that I have).
