When upgrading from SOI 3.2 CU3 to SOI 3.3 CU2 on a Spectrum connector system using the the ‘soi-installer.exe’
from the SOI 3.3 DVD, I receive the error message below.
"Invalid Installation Attempt
Cannot upgrade version 126.96.36.1999.20141022 to 188.8.131.52
The currently installed features cannot be upgraded by this installer
Please select ‘OK’ to Exit."
The IntegrationServices.exe and IntegrationServices.iam.zip files from the ..\SOI folder on the SOI 3.3 DVD
should be copied to the connector system and used to upgrade SOI on that machine.
