When I try to enable CorelPolyGUI 1.4.4, I get this message. How can I correct this? Thanks
Under v4.2 there may now be little need for the CorePolyGUI extension. Refer the answer here. Which operating system, LO version, and Java version are you running?
CorePolyGUI now offers v1.4.5. This recent update may address this particular issue, although it does not appear to mentioned in the changelog. There has been a reported issue (fdo#63223) about an erroneous upgrading process that cause this type of problem with extensions. It sounded quite horrible and was closed due it being mainly extension-related. The solution in this case would be to uninstall and re-install LO. I am not sure though if this is related to your error unless you are getting a crash.
