Hello,
It's the lifetime license with the 2-year free update support.
After the 2-year free update support, you cannot update to any new version but you can still use the old versions of the software.
Please try to contact me with your order information via jaychivo@extendoffice.com.
For this error "an 'access violation' error", please try to disable all the other add-ins in your Excel add-ins manager.
I need a working link for previous version of Kutools for Excel. The link supplied in the registration windows shows the 504 error. I'm asking for cost or price of upgrade option related to my license.
Could you give me a working link to download the previous version of Kutools for Excel? My license expired in June 2017.
