PRTG Administration Tool




We noticed that in Start menu on our Windows server the "PRTG Administration Tool" icon is missing. It seems that our AV tool has deleted the .exe file, so now we can't get/start PRTG Administration Tool.

Is there any way to just reinstall PRTG Administration Tool, or we have to do the complete re/installation again? We would like to keep all historic data.

Thank you.

Thank you for your message.

Regarding the issue you experienced, I recommend to configure the installation folder of PRTG ("C:\Program Files (x86)\PRTG Network Monitor\") in the whitelist of you anti-virus. Usually, anti-virus move the suspicious file in quarantine, and therefore allows you to get the file back.

If it's not the case, then I invite you to execute the installer of your version to reinstall PRTG Administrator. You will find the installer under "C:\Program Files (x86)\PRTG Network Monitor\PRTG Installer Archive". Before executing it, please stop both PRTG services under PRTG Administration Tool > Service Start/Stop to avoid any issue.

The Data folder won't be modified/removed by the installer, it will only replaces all PRTG files (and add PRTG Administrator.exe) in the installation folder.

If you have questions, let us know.

Thank you for the instructions. We made an ad-hoc backup, just in case. Then followed the above procedure, insert license data, all sensors and historical data retained. Everything working normally.
