Install the portable version of 7.18 and see if it runs with no settings changed. If it runs, then there could be a problem in your settings. Copy the install calibre settings to the settings directory in the portable directory. If the portable version then will not run, Then rename all.json files to .jason.bak and if calibre runs then rename them back .json one-by-one until calibre fails to run and then you know where the problem is.
