Hi Raj Kumar Katta,
Actually it’s not an error it says that you have to use new version of mendix studio pro 9.18.4. Please check the latest version of modules and download it.
When you are trying to download any module, make sure to check the Mendix version it supports. The latest version of Excel impoter v 10.3.0 supports Mendix 9.18.4 and above. You need to download v 10.2.0 which suports Mendix 9.0.5 and above.
