Since Isah 4.0, Crystal Reports reports have been phased out and replaced. In Isah 4.7 all standard Crystal Reports reports have been replaced by alternatives. If you perform a standard installation of Isah version 4.7, the Crystal Reports link will not be installed.
To be able to use Crystal Reports for custom reports, specify during the installation of Isah that you want to install the Crystal Reports link. In that case, you also need to install Crystal Runtime or Designer (see Installation Guide Crystal Reports).
If you install the Crystal Reports link, the Isah application is not compatible with DEP (DEP is a Microsoft Windows feature protecting computers against security threats such as viruses), and you will get an error message when you try to print custom Crystal Reports reports. To solve this issue, disable Windows DEP for Isah (see the procedure for DEP on the Isah Support Site https://support.isah.com/tas/public/knowledgebasebrowse?unid=7669514d4690401bb4f954ef67c70a7b).
