system hangups using vb .NET with .NET4.5

I have a very large, multi-form VB .NET program using Visual Studio 10 (VB) and .NET 4.0 with SQL Server - it works well and quickly
When installed on a .NET 4.5 machine there is a 30 - 60 second pause when loading a new form into a MDI interface for BUILT applications, not apparent in debug mode on development PC.
This is still present when compiled with VB13 and targeted to .NET 4.5.1
The code just executes a load command, previously instantaneous. Something must have changed in the memory management with .NET 4.5
How can I restore the short load times, please?

you did not provided any error message.

if you did not handle errors then you can retrieve error Message from Control Panel->Administrative Tools -> Event Viewer.

No error messages, just long delays loading forms.
Further investigation shows that checking box 'Prefer 32 bit' in properties overcomes the effect.
However, I am running a 64 bit system - so seems nonsensical

Using WIndows 8 or Server 2012 .NET 4.5.1 and vb13:

1. I built for x64 and it was slow to load forms when built - but fast in vb13 development mode
2. Ticked (checked) 'Prefer 32' and it was fast when built.
'Prefer 32' was grey when project converted from vb10 to vb13 so started new project and imported all forms etc. to recover the ability to use this option.

This all seems inconsistent - am I missing something?
I want a fast build that can be used both with .NET 4.0 and .NET 4,5,1 on 32 and 64 bit systems. A LOT of windows XP systems still out there!

so, as I've 'sort of' solved the problem myself, but VERY inelegantly, the question now is:
'How should I be doing this to get a single, fast and inclusive project?'

This worked, although seems a compromise. No-one suggested anything better.
