There is an issue with Crystal reports support with Plesk installation . We have found that in spite of installing the crystal report runtime redistributable package the report won’t show in the web page on any hosted domain in Plesk, but if you run the report under a virtual directory under the default website the report will be displayed properly. The reason behind this is the IIS application pool launching user (identity). By default the “Default Application pool” launches using the “Network Service” privilege which has the privilege to access the Crystal report assemblies that are referenced in your web.config file. By Default when a domain is hosted through Plesk control panel it creates a separate application pool for it and the user to launch its application pool is set to “IWPD_domain”. So to resolve the issue either one has to change the application pool Identity to “Network Service” or create a separate application pool using “DefaultApppol” as template and then change the application setting of the website to use that newly created application pool. Remember to set inheritable NTFS permission to the “Network Service” user on your web site.
You can download the crystal report redistributable packages from the link and install it:
