How can I upgrade Splunk Enterprise 6.6.8 to 7.1.1 in Windows Server?

New Member

to test the upgrade process, we created a clone of our current splunk server (6.6.8 running on Windows Server 2016) via VSphere (using VMWare 5.5).
During the upgrade process I get the following errors:
"The program can't start because SSLEAY32.dll is missing from your computer. Try reinstalling the program to fix this problem"
"The program can't start because LIBEAY32.dll is missing from your computer. Try reinstalling the program to fix this problem"
The the upgrade is rollbacked.
I just did the upgrade from 6.6.3 to 6.6.8 last week without any problems.
What can I do to perform the upgrade successfully?

I saw similar issues, and like the others have said try a fresh install and see if that also fails to verify your environment vs. the upgrade.

Hi BerndS,

validate the checksum of the downloaded install package, or download it again. I saw such messages before, and when trying with a new downloaded package it was working.
If it still fails for you, you might have a deeper issue on your server (like corrupted file system or a like) but that would not be Splunk related.

Hope this helps ...

cheers, MuS
