Probably the Web Activity Package version you are trying to install from package manager is a upper version and not supported by studio version 2017.1. solution for that is to update your Studio to latest version and try installing the package again.
Some dependent dll is os in higher version not supported by the UiPath Studio v2017.1. upgrade your studio or use any lower version of the web.activities package.
Hello. Sure. Let me try to upgrade the version from uipath 2017 to 2018. Can you please provide me a link from where I can download the latest uipath version? (enterprise edition) ?
Solution : Install Uipath.web.activity version 1.2.6863.33980
explanation:
you are getting this error 'Rest Sharp (>= 106.3.1) because you are trying to install Higher version of Uipath.web.activity
