====== Install and upgrade applications ======

Applications can be deployed and upgraded in two ways:

  * with [[AppCentral]]
  * manually from inside Innomatic applications panel

===== Application installation troubleshooting =====

**Q. Innomatic hangs after the installation or upgrade of a application.**

A. The installation/upgrade process has been interrupted and the lock file
WEB-INF/temp/upgrading_system has not been removed. Remove it accessing 
[Innomatic Web URL]/root/unlock from your browser.

**Q. Since Innomatic archive size is greater than 2 megabytes I'm unable to
update it in the applications administration page.**

A. The standard PHP upload file size limit is set to 2M. Increase it to a value
bigger than the Innomatic archive, e.g.: upload_max_filesize = 8M
