I try to install a new PRTG version on my Windows Server 2003 system using the auto-update. Unfortunately, the update cannot be installed. The PRTG log shows the following message:
03.02.2016 13:09:33 Match: C:\Program Files (x86)\PRTG Network Monitor\download\PRTG Network Monitor 18.104.22.1686 Setup Commercial (Stable).exe
03.02.2016 13:09:33 Could not read Version info, try again... (C:\Program Files (x86)\PRTG Network Monitor\download\PRTGServerUpdate_tmp.exe)
03.02.2016 13:09:33 Could not read Version info for 5min (C:\Program Files (x86)\PRTG Network Monitor\download\PRTGServerUpdate_tmp.exe)
The Digital Signatures property of the PRTG installer in the download folder shows the following message:
The integrity of this certificate cannot be guaranteed. The certificate may be corrupted or may have been altered.
Why can’t I install the update? Is it because there is no more support for Windows Server 2003?
