An APS installation is stuck. It does not fail, but seems to do nothing at all.


This issue is caused by multiple unfinished sappmng processes.


Please do the following:

  1. End multiple stuck sappmng processes:

    Start > Run > cmd > taskmgr.exe > go to Processes tab > right-clink on `sappmng` > End Process Tree
  2. Clean up the psa.longtasks table:

    "%plesk_bin%\dbclient.exe" --direct-sql --sql="delete  from longtasks"
  3. Clear the application cache:

    Tools & Settings > Applications & Databases > Application Vault > Clear Cache
  4. Try to install the desired APS again.
