Hi

Install Module

Go to Settings >> Modules >> Apps >> Click on install button 

If you want install you custome module then

Settings >> Modules >> Update Modules List  Po-pup will open Click on Update button then

Go Settings >> Modules >> Install Modules 

 Remove Install module and search your module name open your module and click on install button

Uninstall Module

Go Settings >> Modules >> Install Modules

Search your module open it and click on uninstall module 

quicker/easier way:
-->from psql:
--------> update ir_module_module set state='uninstalled' where name='your_module';

(this is not realy uninstaling the module, or deleting views.. it just marks module 'uninstalled' ) 
Use this method if your database is broken after instaling/upgrading module and you can't login anymore...
