Why am I getting this error after migrated to a new machine? Thanks

I have a web project working well in my old laptop, I was recently assigned a new laptop to replace the old one, surprisingly the working project failed to compile, it prompts lots of errors like:

Name "IIF" is not declared
Name "Mid" is not declared
Name "Chr" is not declared
...
What happened to my migration? How can I fix it? Thank you very much.
