  • Plesk 7.6 for Windows


Site application installation fails with the following error:

Error: SiteAppPackagemanager::installSiteAppRunPreinstallScript() failed: cSiteAppManager::sappmng_run_application_package_script(SITEAPP_SCRIPT_PREINSTALL) failed:Unhandled exception


File permissions Plesk bin folder for Plesk users in psacln group are not enough.


File permissions need repairing using the Plesk reconfigurator:

Start, Programs, SWsoft, Plesk, Plesk Reconfigurator, Repair Plesk Installation, tag only Plesk File Security option, click on Check button.
