if EXISTs(SELECT 1 FROM Framework.Service WHERE ID = 'B0ED76DD-F93B-4B64-8E87-654129E2A8AC' AND DeploymentID = 'D6726F6A-10A0-4917-AFD3-21949A62CD51')
begin
--print 'x'
Update Custom.Membership
set membershiptype = 'Unlimited/Ongoing' where Ongoing = 1
end

Here condition is false still it tries to set membershiptype column which does not exists and throws the error.

See with else part then you can get the point where it is missing if condition in your nested query

IF EXISTS(SELECT * FROM Framework.Service WHERE ID = 'B0ED76DD-F93B-4B64-8E87-654129E2A8AC' AND DeploymentID = 'D6726F6A-10A0-4917-AFD3-21949A62CD51')
begin
	--check whether ma package is not installed
	IF NOT EXISTS(SELECT * FROM Framework.Service WHERE ID = '764AE521-320E-4B90-A9F7-5C7614C5C28E' AND DeploymentID = '3015C5DB-DE04-4B73-89BF-AEDE95F3D9F8')
	begin 
		if exists (select * from [Framework].[Object] where id = '8AC96BD2-9550-486B-804E-A40D0C57D6EC')
		begin --go
			Update Custom.Membership
			set membershiptype = 'Unlimited/Ongoing' where Ongoing = 1
		end
		else begin
			select 'else part of last nested if'
		end
	end
		else begin
			select 'else part of second nested if'
		end
end
else begin
	select 'else part of first nested if'
end
