# How to update Calc on Windows

Asked by PekkaH on 2015-02-13

Hi, What is the best way to update Calc. My version is 1.0-a24 (text in Calc window). Should I export workspace before updating the system.

Cheers,
Pekka

Hi Pekka!
At the moment, the only way is to first uninstall the old version, and then install the new one.
You can uninstall Calc from the Windows control panel.

You don't need to export the workspace, because all the data are stored in the postgres database (unless you are re-installing postgres as well, but maybe it's not your case)

Thank you.
Mino

Hi,
Warning. If you have created and saved SAIKU queries, and you want to reuse them, so before uninstalling Calc you need to take a copy of folder:
***..\calc-server\tomcat\webapps\saiku\WEB-INF\classes\saiku-repository***

These saved query files are (not yet) transfered with the installation. Mino has noted this at [https://github.com/openforis/calc/issues/6][1]

Best, Lauri
