BizTalk 2013 Installation Bug: Enterprise Single Sign-On Error

While Installing BizTalk I received the following Error that Enterprise Single Sign-On should be installed manually.

Well this had not occured while installing previous versions of BizTalk. So I was a little bit curious as to what am I missing on the Server.

So I started installing the redistributable prerequisites manually as this is what BizTalk installation does first.

What I noticed is 

After installing .Net Framework 4.5 from the .cab file I tried to run the BizTalk installation again as normal and selected the .cab file I downloaded.

And it worked fine and BizTalk 2013 was installed successfully with Enterprise Single Sign-On and all other features.

So seems Enterprise Single Sign-On  installation needs .Net Framework 4.5 to be in  place before it can be installed and BizTalk Installation is messing it up somewhere while installing the redistributable prerequisites.

BiztalkR2 Installation issues

 Installing Biztalk 2006 R2 upto perfection on Multi Server Environment is still a nightmare.
Ideally Biztalk Configuration Management should take care of Basic configurations.
I had to use Custom Configuration Settings to configure it.
Errors I encountered and Resolution.
Business Rule Engine got installed successfully without any errors.
I had Errors with Group and Biztalk Runtime.
Errors with Groups.
Biztalk UserID needs enough rights on the Server.Make sure the Uer is a sysadim on the Server.

Errors with Runtime.
ONe was regarding SQL Server douesnot exist,Database file is not deleted.
Resolution.
In my case Configuration had failed previously,so there were few database files inside MS SQL/Data folder which needs to be deleted.

Creation of Adapter FILE Configuration Store entries failed biztalk runtime configuration.
Just Start the RPC-Local Service inside Windows Services Manager.
Note-There are 2 RPC Services.

After installation I saw few errors in Eventlog.
If you get an error in Eventlog Regarding Some TDDS locks on any of the Biztalk Databases.Refer following link for solution.

I even had issues with Visual Studio 2005 SP2.
error 2755.
I was executing the exe from C Drive.
I just copied it to D Drive and executed it from there....worked fine.Seems some encryption is causing problems for the exe to execute from C Drive.
