Version 8 UK. I had a hard drive crash, but was able to restore to a back-up, but Generations would not load. I tried to reinstall over my restored data, but got two error messages. The first said "Uninstaller failed to Initialise, you may not be able to uninstall this product", then right at the end of the install process I got the error message 115 above, and the information "More Dlls" and the filename comdlg32.ocx. I tried completely wiping my Sierra directory, and trying a clean re-install, but got the same problem. Can anyone help me with this, please?
