Visual Studio 2017 Problem

hi,

 As @Manav said enterprise version is licenced, you will get only 30 dys trial, before this trial period runs out you have to activate vs with key, after 30 days you can not able to activate with key, you have to un install and install it again and you have to put key,or try below

for free you can use vs community edition which is completely free without expire.

Register your VS by providing the license key.

You may use the Visual Studio Code, the lighter version. 

Hello

 

Enterprise version mainly used for organization with license

 

If you want to use for non-commercial , than install vs 2017 community eddition which is free

 

Thanks
