Thanks for pointing this out. I must admit I have never used the installer to install Wave Corrector on a Linux PC. Instead, I have simply manually copied the Wavecor.exe file to the Linux machine.
I've just tried using the installer program and I get the same access violation that you report.
Doing a little Googling, I've discovered that the problem arises because the installer program in incompatible with Wine's built-in riched20 DLL.
The solution is to place a copy of the Windows DLL in the Windows/system folder on the Linux machine and to run the installer with the following command line
WINEDLLOVERRIDES="riched20=n" wine wcor_31.exe
