When I Install 4.3 I get a blank page?

Be sure you have .... "nopCommerce requires write permissions for the directories and files described below:

For nopCommerce versions 4.00 and above:

\App_Data\
\bin\
\log\
\Plugins\
\Plugins\bin\
\wwwroot\bin\
\wwwroot\bundles\
\wwwroot\db_backups\
\wwwroot\files\exportimport\
\wwwroot\images\
\wwwroot\images\thumbs\
\wwwroot\images\uploaded
\App_Data\Plugins.json (after installation)
\App_Data\dataSettings.json (after installation)

Has it created the database schema?

has it created a dataSettings.json file in App_Data? Is the connection string in there valid? or blank "" ?

I think i've seen this happen when it has created the file but with no connectionString set.

The data connection string is null

Ok, - If you have a blank database (no tables created), delete dataSettings.json and try Install again

The tables are there

I am trying to enter the values manually.

it did not like it so must be putting it in wrong lol

{
"DataProvider": "sqlserver",
  "DataConnectionString": "Data Source=<YOUR-DATABASE-INSTANCE>;Initial Catalog=<YOUR-DATABASE-NAME>;Persist Security Info=False;User ID=<YOUR-DATABASE-USERNAME>;Password=<YOUR-DATABASE-PASSWORD>;MultipleActiveResultSets=True;Connect Timeout=30;Encrypt=True;TrustServerCertificate=True",
  "RawDataSettings": {}
}

You also need 2 back-slashes if for example its SERVERNAME\INSTANCENAME

That worked great but I may have to install again I get the following:

So I guess it did not do it right.

Will delete database and start again.

Yep. Start with a blank db, delete the datasettings.json.  When it's installing give it plenty of time even if screen goes blank/timeout etc. maybe wait 5-10 mins before refreshing or restarting app pool.  Even after restart, be patient as I think it runs a lot of db creation stuff after the restart which you don't want to interrupt
