# Sitecore 10.2 installation guide
## Installing Sitecore 10.2
- Download the "Graphical setup package for XP Single" from https://dev.sitecore.net/Downloads/Sitecore_Experience_Platform/102/Sitecore_Experience_Platform_102.aspx
- Extract the contents of the zip somewhere on your PC.
- Run the .exe installer.
- As you run through the steps make sure to install everything when prompted. (I gave my instances -eg. solr isntance a name like "sc102"). You are also asked for your sa db password (in most of our cases, this will be 'H3mm3ligT').
- Let the installer run it's course.
- Once it's done you get a button that will open sitecore and this should run just fine now.
## Installing Ucommerce
Seems like default database users provided by the installer do not have enough permissions to install Ucommerce. (I don't think this is a new thing in Sitecore 10, I believe it has been the case for a long time.) - hence the first step.
- Before installing Ucommerce, edit every SQL connection string in your website folder (dev.local only) /App_Config/ConnectionStrings.config to use `sa` as the user id, and your admin password (our default test password `H3mm3ligT`).
- Install the Ucommerce.Sitecore zip package the same way as with any other previous version.
- This seemingly works fine. At this point I verified speak apps, the "start menu" shortcut and some of the UIs and integration points (eg. users in settings)
## Installing Avenue Clothing for Sitecore
- Install the latest Avenue Clothing for Sitecore zip package.
## Installing another instance of Sitecore (Once all prerequisites are already installed)
- Run the .exe installer again
- Give your site a different instance name
## Troubleshooting
Try to use Solr version 8.8.2 (latest for sitecore 10.2 at this point)
If you don't have permissions to your C:\ drive try adding new partition drive and run the installation from there. (Mainly Solr issues)
