User-added image
CauseIn 6.6 or higher, the Caching service is obsolete and so is the GemFire module. However, the Archer installer fails to clean up the GemFire related files from the Archer folder. Default is C:\Program Files\RSA Archer\Archer Control Panel\Plugins.
Resolution
  1. Go to the Plugins folder location.  Default is C:\Program Files\RSA Archer\Archer Control Panel\Plugins
  2. Find all the files related to "GemFire".  Here are known files:  


ArcherTech.ControlPanel.Plugins.GemFireCacheMonitor.exe
ArcherTech.ControlPanel.Plugins.GemFireCacheMonitor.exe.config
GemStone.GemFire.Cache.dll
GemStone.GemFire.Cache.xml
Gemstone.Gemfire.Plugins.SQLite.dll
gemfire.ico


  1. Delete or move files to a different location.
  2. Restart RSA Archer services.
  3. Reload the Archer Control Panel.
