Excel reader and writer no longer available

KNIME Extensions
1

Help! I just updated to a newer version of knime 4.1.2. I was working on some workflows with excel file readers and writers.

After update I tried opening a workflow I was previously working on earlier today and I get the following:

ERROR LoadWorkflowRunnable Errors during load: Status: Error: OTC_SWAPS_PRICING 0 loaded with errors
ERROR LoadWorkflowRunnable Status: Error: OTC_SWAPS_PRICING 0
ERROR LoadWorkflowRunnable Status: Error: Node “Excel Writer (XLS)” not available from extension “KNIME Excel Support” (provided by “KNIME AG, Zurich, Switzerland”; plugin “org.knime.ext.poi2” is not installed)
ERROR LoadWorkflowRunnable Status: Error: Node “Excel Reader (XLS)” not available from extension “KNIME Excel Support” (provided by “KNIME AG, Zurich, Switzerland”; plugin “org.knime.ext.poi2” is not installed)

ERROR LoadWorkflowRunnable Status: Error: Node “Excel Writer (XLS)” not available from extension “KNIME Excel Support” (provided by “KNIME AG, Zurich, Switzerland”; plugin “org.knime.ext.poi2” is not installed)

It seems I can’t even find the Excel extensions. Basically all my workflows have excel readers / writers.
Anyone else got this?

Didn’t solve this - went back to version 4.1.0 (uninstall and re-install) workflows seem to work again. Won’t be update back to 4.1.2 anytime soon.

When you updated, did you download an entire new KNIME from knime.com or did you update from within KNIME (? version 4.1.0 ?) ?
