# Why don't some functions work in trial versions of Mathematica?

I currently use the trial version before I decide to upgrade. However, a number of expressions don't work, i.e. it results in some errors that I don't know how to interpret. For example, if I use the simple GeoGraphics[] expression from the help menu, it results in the error message

General::unavail: ExportString is not available in this version of the Wolfram Language.


This error pops up in multiple contexts (e.g. other Geo-expressions, CloudDeploy, etc.) and I have no clue why.

It's because you have the trial version. Some features, including anything to do with exporting, are crippled in the trial version. –  m_goldberg Jul 13 at 15:33

@JacobAkkerboom There are a number of duplicates of this. I would think it makes sense to keep one question around with an answer (this one, for instance) and just close the rest as duplicates. –  acl Jul 13 at 17:50
@acl agreed. I will retract the vote then. –  Jacob Akkerboom Jul 13 at 18:08
