We are troubleshooting an unrelated environmental error, and this question was asked, as we recently upgraded to Octopus 2.6.2.845, and the subsequent Tentacle upgrade activity coincides with start of the issue.
The question for you: Would the Octopus Tentacle update have installed, modified or registered MSCVR90.DLL on the machines?
This .DLL file apparently comes from the Visual C++ Redistributable package.
One more question Henrik – does the Tentacle application use MSVCR90.DLL at all? (This DLL is related to the Microsoft Visual C++ Redistributable.)
In other words, do I need to have MS Visual C++ in order to install and run Tentacle?
