Experience running OMERO 5.2.1 under Windows 2012 ?

Postby KBernhardt » Fri Mar 18, 2016 3:47 pm

Do you have any experience running OMERO 5.2.1 under Windows Server 2012 R2, all componets installed in 64bit version?

We are running into trouble starting the /OMERO Website.

It shows only: "This page can’t be displayed" and the Windows System Log shows:

„Source: Microsoft-Windows-WAS, Event ID: 5009
A process serving application pool 'DefaultAppPool' terminated unexpectedly. The process id was '7700'. The process exit code was '0x1'.„

It seems to be a problem with IIS 8.5 (DefaultApplPool) with _omero_web_iis.dll

We tried several Test Installations on Server 2008R2 and 2012 R2.
At the 2008 R2 Servers the website shows up as expected, on 2012 R2 Servers the error mentioned above shows up.
Details of the installation are attached below.

Can you give us a hint what to try next?

Thanks a lot in Advance,


All components are installed as 64bit versions

Omero 5.2.1
PostgreSQL 9.4
Python 2.7
Ice 3.5

IIS: Default Application Pool - Enable 32-Bit Applications false

the problem is Python 2.7.10. You have to downgrade that to 2.7.9 as stated in the documentation https://www.openmicroscopy.org/site/sup ... l#python-2

Note that reinstalling python my require reinstalling all other dependences and restating the machine
