It's not. I deleted the .wine folder and created a new one by running winecfg. I'm just giving these details in case I'm doing something wrong here. I soon after attempted to run the installer and, once again, got this: Code: wine ESDPK-WPX5-WebPlusX5-EN.exefixme:storage:create_storagefile Storage share mode not implemented. err:msi:ITERATE_Actions Execution halted, action L"LaunchConditions" returned 1603 So there is nothing that can be done?
