# Missing Reference for HTTPRequestHandler , Text , RichMail , RichWidget

Hi all,

I have tried to upgrade one application that developed by outsystem version 6 to version 7 . when i try to publish the application i am getting error like " Missing Reference " for  HTTPRequestHandler , Text , RichMail , RichWidget .

how can i fix this issue. is that possible to download from outsystem?

Thanks in advance,

Hi Prassin

HTTPRequestHandler, Text, RichMail and RichWidgets are all modules that are part of System Components. If they are missing, it seems your environment is missing that solution.

I would suggest you proceed as follows (from the install checklist):

After that, you should be able to publish the original "version 6" component and it should upgrade!

Let us know how it goes.

Cheers,
